When you’re travelling the vast and varied landscapes of Australia by RV, one thing becomes clear quickly: a reliable, easy-to-manage toilet setup is absolutely essential. Whether you’re cruising coastal highways, setting up camp in the bush, or free camping in a remote gorge, having the right kind of toilet can mean the difference between convenience and constant stress.
In Australia, RV travellers typically face three main toilet options: cassette toilets, composting toilets, and the good ol’ drop toilets found at many free camps and national parks. Each comes with its own pros, cons, and best-use scenarios depending on how you travel, how often you’re off-grid, and how much maintenance you’re willing to handle.
This guide will walk you through a detailed comparison of cassette vs composting vs drop toilets—specifically for Australian conditions. We’ll explore environmental considerations, dump point access, hygiene concerns, legalities, and traveller comfort. Whether you’re a weekend warrior renting a campervan, a grey nomad on a lap of the map, or an off-grid vanlifer exploring wild Australia, this guide will help you choose the toilet setup that suits your travel style—and your guts.
Let’s flush out the facts, so you can make the most hygienic, cost-effective, and eco-conscious choice on the road.
Why RV Toilet Choice Matters in Australia
Australia’s sheer size and diversity of landscapes mean you can go from bustling urban parks to remote red dirt campsites in a single day’s drive. But with this freedom comes a unique set of challenges—especially when it comes to waste disposal. Choosing the right RV toilet isn’t just about comfort; it’s about compliance, sustainability, and practicality across vastly different environments.
Legal & Regulatory Considerations
In Australia, many campgrounds, national parks, and rest areas require RVs to be self-contained—especially if you plan to free camp. This means having your own toilet system onboard is often a legal requirement, not just a convenience. Some local councils strictly prohibit overnight stays for vehicles without onboard toilets, and fines can apply if you’re caught emptying waste incorrectly.
Dump points (the facilities designed for safe disposal of toilet waste) are widely available in towns and RV parks, but they’re far less frequent once you get into the Outback. So, your toilet system needs to work with the realities of limited infrastructure, especially in remote regions.
Environmental Sensitivity
Many of Australia’s most breathtaking locations—think Kakadu, the Kimberley, the Flinders Ranges—are also environmentally fragile. Improper waste disposal can pollute waterways, attract wildlife, and damage native vegetation. Composting toilets are often favoured in these regions for their low impact, but not every system suits every traveller.
Drop toilets (long-drop, waterless systems managed by councils or park rangers) are common in free camps and national parks. While convenient, they’re not always clean, and you can’t rely on them to always be available or usable. That’s why having your own toilet—whether chemical, composting, or portable—is often a necessity.
Urban vs Remote Access
In cities and popular tourist hubs like Sydney, Byron Bay, or the Gold Coast, dump stations and caravan parks with full amenities are easily accessible. For weekend RVers or short-term travellers, a simple cassette toilet might be all you need.
But once you venture into inland Queensland, the Pilbara, or Tasmania’s rugged west coast, public facilities thin out quickly. Here, having a system that doesn’t depend on frequent emptying or chemical waste disposal—like a composting toilet—can offer unmatched flexibility.
Travel Style Dictates Needs
Grey nomads on the Big Lap might prefer low-maintenance solutions they can use daily without relying on external services.
Full-time vanlifers often prioritise eco-friendliness and long gaps between waste disposal.
Weekend campers may be happy to rely on public drop toilets, so long as they’re clean and accessible.
Your RV toilet choice isn’t one-size-fits-all—it’s about matching your system to how, where, and why you travel across Australia.
Cassette Toilets Explained
Cassette toilets are the most common type of toilet found in caravans, campervans, and even some motorhomes across Australia. Known for their compact design and ease of use, they’re a familiar system to many travellers—especially those who’ve hired a van or stayed in a caravan park before. But while they’re popular, cassette toilets aren’t perfect, and they come with their own pros and cons worth understanding.
How They Work
A cassette toilet is a self-contained unit that consists of two main parts:
A flushable toilet bowl that looks much like a domestic toilet (though usually made of plastic), and
A removable waste-holding tank (the “cassette”) located underneath or behind the toilet.
The toilet is flushed using either a manual pump or an electric system, pushing waste into the cassette tank below. Once full (usually after 2–4 days of use depending on capacity), the cassette is removed—typically via an exterior hatch on the RV—and emptied at a designated dump point. Chemical additives are usually added to the tank to break down waste and reduce odour.
Pros of Cassette Toilets
User-Friendly: The experience is similar to using a regular toilet. Easy for new RVers to understand.
Compact Size: Fits in small vans and caravans without requiring extra space.
Widely Accepted: You’ll find compatible dump points across most of Australia, from metro parks to Outback roadhouses.
Inexpensive Setup: Most RVs come pre-installed with cassette toilets, saving upfront investment.
Cons of Cassette Toilets
Chemical Dependency: You’ll need to carry and use toilet chemicals, which can be toxic or non-biodegradable if not chosen carefully.
Frequent Emptying: Small tank sizes (usually 10–20L) mean you may need to empty every couple of days, especially for families or couples.
Odour Risk: If not cleaned regularly or if cheap chemicals are used, the tank can develop strong odours—especially in warm climates.
Not Ideal for Long Off-Grid Stays: Regular access to dump points is essential, which can be a challenge in remote areas.
Best Suited For
Short trips (weekends or up to a week)
Travellers staying in caravan parks or near dump stations
Rental vans and urban-based RV trips
Those who want a familiar, flush-style toilet
Cassette Toilet Tips
Use biodegradable or Australian park-approved chemicals like those by Thetford Aqua Kem Green or Bio-Pak.
Empty the tank before it’s full to avoid spillage or bad smells.
Rinse after every dump to keep the tank fresh and clean.
Carry spare chemicals and a pair of gloves for hygienic emptying.

Cassette toilets are the go-to option for many Aussie RVers simply because they’re convenient, proven, and accepted nearly everywhere. But as we’ll explore next, they’re not always the most sustainable—or most off-grid-friendly—solution.
Composting Toilets Explained
Composting toilets have become a popular alternative for eco-conscious travellers and full-time RVers who want to minimise their environmental footprint and maximise off-grid independence. Unlike cassette systems that rely on chemicals and dump stations, composting toilets treat waste naturally—turning solids into compost and diverting urine for easier disposal.
Although more complex and often more expensive up front, composting toilets offer unmatched sustainability for those travelling deep into the bush or living full-time in their RV.
How They Work
A composting toilet separates liquids (urine) from solids (faeces) to control odour and accelerate decomposition. Solids drop into a chamber that’s typically lined with a carbon material like coconut coir or sawdust. Urine is diverted into a separate container that must be emptied regularly—often every 2–4 days depending on usage.
Ventilation fans and drainage systems are used to maintain airflow, reduce moisture, and assist in the composting process. The solids chamber can last 2–6 weeks before needing to be emptied, depending on the number of users.
The result? No nasty chemical smells, no black water tanks, and no dump points needed.
Pros of Composting Toilets
No Chemicals Needed: Environmentally friendly and better for greywater ecosystems.
Longer Emptying Intervals: Solids need to be emptied far less often than cassette toilets.
No Dump Point Required: Can be emptied into compost bins or buried (where permitted).
Great for Off-Grid: Ideal for remote travellers who won’t have access to services for days or weeks.
Odour-Free When Maintained: Contrary to what most assume, composting toilets often smell better than chemical ones when used properly.
Cons of Composting Toilets
Higher Upfront Cost: Expect to pay anywhere from $1,200 to $2,500 AUD for a quality system.
Larger Footprint: Requires more space than a cassette toilet—better suited to motorhomes and large vans.
Manual Management: You’ll need to monitor moisture levels, maintain ventilation, and manage compost materials.
Not All Parks Approve: Some national parks don’t allow solids from composting toilets to be disposed of onsite. Always check regulations.
Best Suited For
Full-time travellers or those living in their RV
Off-grid and remote-area campers
Environmentally conscious vanlifers
Larger vans and motorhomes with space to accommodate the unit
Composting Toilet Tips
Use coconut coir or peat moss to balance moisture and support decomposition.
Install a good ventilation fan to keep air flowing and prevent smells.
Divert urine responsibly—many RVers dilute and dispose in approved greywater drains.
Empty solids into a compost bin where permitted, or double-bag and bin as a last resort.

Drop Toilets in Campsites
While cassette and composting toilets travel with you, drop toilets are fixed facilities commonly found in national parks, remote campgrounds, and free camps across Australia. Known for being low-tech but effective, these toilets provide a minimal waterless solution for managing human waste in off-grid public areas.
For many RVers—especially those travelling light or without an onboard toilet—drop toilets are a convenient fallback. But they come with limitations, and relying solely on them isn’t always practical.
What Are Drop Toilets?
Drop toilets (also called “long-drop toilets”) are non-flushing, waterless toilets that collect waste in a large pit or tank beneath the seat. They’re often housed in simple concrete or timber huts and may be managed by local councils, state park services, or community groups.
They don’t use chemicals or water and depend on natural decomposition, occasional pumping, or replacement of the pit when full. Ventilation pipes help minimise odours, and many are fitted with solar-powered fans for airflow.
Where You’ll Find Them
National parks across Australia (e.g., Grampians, Daintree, Karijini)
Remote free camps listed on WikiCamps and CamperMate
Roadside rest stops in rural regions
Council-run bush camps and showgrounds
While widespread, they’re not guaranteed. Some remote campsites don’t have any facilities at all, making a personal toilet system essential.
Pros of Drop Toilets
Free to use: Most are part of public infrastructure, especially in national parks.
No waste management needed on your part: You use it and leave.
Low environmental impact (when maintained): Uses no chemicals or water.
Better than nothing in remote areas: Particularly helpful if you don’t carry a toilet onboard.
Cons of Drop Toilets
Variable cleanliness: Some are well-maintained; others are neglected and unhygienic.
No flushing or handwashing facilities: Often no running water available.
No guarantee of availability: Relying on drop toilets alone can backfire, especially during peak season or in lesser-visited regions.
Not suitable at all for overnight vehicle stays without toilet onboard in restricted zones.
Drop Toilet Etiquette & Tips
Always carry toilet paper—many drop toilets run out or don’t stock any.
Use biodegradable wipes sparingly and never flush them, even in drop systems.
Close the lid after use to keep smells down and prevent fly breeding.
Bring hand sanitiser, especially in remote locations.
Never dump RV toilet waste into a drop toilet—this can damage the composting system and release harmful chemicals.
Should You Rely on Drop Toilets?
Not entirely. While drop toilets are a helpful supplement, they shouldn’t be your only solution—especially if you’re travelling remotely, free camping, or aiming to be self-contained. Many free campsites now require you to have your own toilet system in place, and drop toilets aren’t always accessible or suitable in emergencies.
Comparing the Three: Cassette vs Composting vs Drop Toilets
When it comes to RV travel in Australia, there’s no one-size-fits-all toilet solution. The best choice depends on your vehicle setup, travel style, environmental values, and how remote your adventures take you. Let’s break down how cassette, composting, and drop toilets stack up against each other across the factors that matter most to Aussie travellers.
Convenience
Cassette Toilets:
Very convenient in urban areas and caravan parks. Emptying is simple at dump points, and flushing makes the experience familiar. However, tanks fill quickly and need frequent emptying—especially with multiple users.
Composting Toilets:
More involved to set up and maintain. You need to manage solids, empty urine regularly, and maintain ventilation. However, with proper setup, they offer long gaps between disposals and fewer odour issues.
Drop Toilets:
Convenient only when available and clean. No setup required—but you’re at the mercy of availability, cleanliness, and other users.
Winner (Short-Term Trips): Cassette
Winner (Off-Grid & Long-Term): Composting
Environmental Impact
Cassette Toilets:
Rely on chemicals that can harm septic systems and the environment if not disposed of correctly. Frequent waste disposal increases ecological footprint.
Composting Toilets:
The most eco-friendly option. No chemicals, less water usage, and solids turn into compostable material (when disposed of properly). Great for reducing strain on dump points.
Drop Toilets:
Generally low impact when well maintained, but misuse or poor maintenance can lead to hygiene and groundwater issues.
Winner: Composting
Cost (Initial + Ongoing)
Cassette Toilets:
Often included in the RV. Ongoing costs include chemicals ($10–20/month), occasional replacement parts, and gloves/cleaning products.
Composting Toilets:
Higher upfront cost ($1,200–2,500 AUD), but lower long-term maintenance. No chemical or dump fees. Might require accessories like fans or urine tanks.
Drop Toilets:
Free to use, but require travelling to specific sites—which may increase fuel costs or route constraints.
Winner (Budget-Friendly Short Term): Cassette
Winner (Long-Term Savings): Composting
Legal Acceptance & Compliance
Cassette Toilets:
Universally accepted at dump points Australia-wide. Meets self-contained requirements in most parks and councils.
Composting Toilets:
Generally accepted, but some parks have rules about how waste must be disposed (e.g., not into compost bins or bushland). Must be emptied correctly into bins or compost heaps.
Drop Toilets:
Legal to use, but relying on them exclusively won’t meet self-containment rules in many locations.
Winner: Cassette (most widely accepted)
Comfort & Hygiene
Cassette Toilets:
Feels closest to a regular toilet. Can be smelly if poorly maintained. Needs daily attention on long trips.
Composting Toilets:
Odourless when properly managed. No flushing water needed. Requires regular airflow and compost monitoring.
Drop Toilets:
Hygiene and smell vary wildly. Some are fine, others are borderline unusable. Often lack handwashing facilities.
Winner (Consistency): Composting
Runner-Up: Cassette (when cleaned well)
Best for Travel Types
Weekend Campers & Short Trips: Cassette Toilets
Full-Time Travellers / Grey Nomads: Composting Toilets
Budget & Minimalist Campers: Drop Toilets (with backup solution)
Eco-Conscious Vanlifers: Composting Toilets
Families in Urban/Coastal Parks: Cassette Toilets
Remote Bush Adventurers: Composting Toilets or hybrid (e.g., cassette + backup portable)
Each system has its place depending on how you explore Australia. Cassette toilets offer reliability and simplicity. Composting toilets give you autonomy and sustainability. Drop toilets serve as convenient backups—but should never be your only plan.
Aussie Dump Point Etiquette & Tips
Whether you’re using a cassette toilet or just emptying greywater, knowing how to use dump points correctly is essential to responsible RV travel in Australia. Poor practices can damage infrastructure, harm the environment, and even get you fined by councils or rangers. Here’s what every RVer should know.
Where to Find Dump Points in Australia
Australia is well-equipped with public dump points, especially along major tourist routes, coastal areas, and near holiday parks. However, in the Outback or inland regions, they become increasingly scarce.
To locate them:
WikiCamps: www.wikicamps.com.au
The most widely used app for locating dump points, campsites, and facilities.Camps Australia Wide: www.campsaustraliawide.com
Offers a directory (online and print) with dump point listings across the country.CamperMate: www.campermate.com.au
Another popular app used by travellers to find toilets, water fills, and dump stations.
Always plan ahead—especially when travelling off-grid for several days.
How to Dump Responsibly
Use the Correct Outlet
Never empty toilet waste (black water) into storm drains or garden areas. Only use designated dump points marked for black water.Wear Gloves
Always use disposable or reusable gloves to prevent contamination.Rinse the Cassette
After dumping, rinse the cassette tank thoroughly with the provided hose (if available). Don’t wash it in sinks or food areas.Use Eco-Safe Chemicals
Choose biodegradable chemicals that are septic-system safe, especially in national parks or rural dump sites.Secure the Lid
Always check that the waste valve is closed and sealed before transporting the cassette back into the RV.Don’t Block the Dump Point
Be considerate of others. Don’t park over the access area for too long if people are waiting.Leave It Clean
Rinse off spills, wipe surfaces, and leave the area better than you found it.
What Not to Do
Don’t dump toilet waste into a greywater-only outlet—it contaminates the system.
Don’t flush wipes, feminine hygiene products, or nappies—even those marked “flushable.” They clog plumbing and damage infrastructure.
Don’t dump in bushland, creeks, or sand dunes—even if your waste is “eco-friendly.” It is illegal and damaging.
City vs Rural Dump Point Availability
Urban Areas: Most caravan parks, showgrounds, and visitor centres offer accessible dump points. Use them regularly to avoid overfilling on short trips.
Remote Areas: You may find dump points at remote roadhouses, community centres, or council-run free camps—but they’re much less frequent. Carry extra waste storage or plan to reach the next town accordingly.
Proper use of dump points not only ensures a cleaner environment, but it also builds goodwill with councils and landowners—helping keep more free camps and self-contained spots open across Australia.
Recommendations: What to Choose Based on Your Lifestyle
The right RV toilet choice isn’t just about the technology—it’s about how, where, and how often you travel. Australia’s diverse travel environments mean that what works well for a city-based weekender might not suit someone doing a year-long lap around the country. Let’s break down the best toilet choice for different types of RV travellers.
Weekend Travellers and Short-Term Campers
If you mostly stay in powered sites or caravan parks and take short trips of 2 to 5 days:
Best choice: Cassette toilet
Why: Easy to use, already installed in many hire vans and caravans, and compatible with widespread dump points
What to know: Carry extra chemicals and gloves, and plan to empty before heading home
Off-Grid and Remote Travellers
If you’re travelling into the Outback, exploring national parks, or camping in places without facilities for more than a few days:
Best choice: Composting toilet
Why: No need for dump points, better odour control, longer emptying intervals
What to know: Learn to manage moisture and ventilation, and ensure you’re disposing of waste correctly and legally
Full-Time RVers and Grey Nomads
If your RV is your home and you’re on the road most of the year:
Best choice: Composting toilet (or cassette toilet with an extended waste solution)
Why: Offers more flexibility, fewer dump stops, and long-term cost savings
What to know: Invest in a quality unit and understand maintenance routines. A hybrid setup (composting for solids, cassette for emergencies) may also be ideal
Families with Kids
If you’re travelling with children and need a reliable, familiar toilet experience:
Best choice: Cassette toilet
Why: Easier for kids to use, requires less supervision, and closely resembles home toilets
What to know: You’ll be emptying it more often, so plan routes with dump points in mind
Eco-Conscious Vanlifers
If reducing your environmental impact is a top priority and you spend most of your time in nature:
Best choice: Composting toilet
Why: No chemicals, less water use, and minimal environmental footprint
What to know: Be sure to comply with local disposal regulations and avoid illegal composting or dumping
Budget-Conscious or Minimalist Travellers
If you’re travelling light, without a built-in toilet system, and mostly stick to council free camps or showgrounds:
Best choice: Drop toilets (with a portable backup toilet)
Why: Free to use, no setup needed
What to know: Always check if toilets are available in advance and carry an emergency option like a basic portable toilet with disposable bags
Final Thoughts
Choose cassette toilets for mainstream, easy-access travel with regular stops
Choose composting toilets for freedom, sustainability, and off-grid independence
Use drop toilets as a helpful backup, not your main toilet solution
If unsure, consider starting with a cassette toilet, then upgrade as your travel style evolves
The best toilet setup is the one that makes your travels smoother, more hygienic, and less stressful—while respecting Australia’s environment and local rules.
Final Tips for RV Toilet Setup in Australia
No matter which type of RV toilet you choose—cassette, composting, or relying partly on drop toilets—your experience on the road will be smoother if your setup is practical, hygienic, and tailored to your travel routine. Here are key considerations and smart add-ons that can make life easier and cleaner while travelling in Australia.
Consider Useful Add-Ons
Ventilation Fans: Especially important for composting toilets, but also helpful in cassette setups to reduce moisture and odour.
Toilet Liners or Bags: Composting toilet users may benefit from biodegradable liners for easier cleanup and disposal.
Spare Cassette Tank: For long trips, carrying an extra cassette tank can extend your time between dump points.
Urine Diverters: For those building a DIY composting setup, a proper diverter is key to managing odour and maintaining hygiene.
Portable Urinals (for emergencies): Useful during long drives or if your toilet becomes temporarily unusable.
Carry a Backup Option
Even if you have a built-in system, things can go wrong—a full tank, broken seal, or blocked vent. Having a simple portable toilet (like a chemical toilet or bucket toilet with double-bag setup) can save you from stressful situations, especially in remote areas. It’s a good idea to store one in your garage or under-bed storage space.
Cleaning and Maintenance Habits
Create a routine: Clean your toilet system at least weekly with non-toxic cleaners.
Rinse tanks after each emptying: This helps prevent residue buildup and keeps smells at bay.
Inspect seals, vents, and hoses monthly: Regular maintenance avoids costly repairs and improves performance.
Keep spare gloves, cleaning spray, and deodoriser in a dedicated toilet kit.
Combining Toilet Options Strategically
Some seasoned RVers use a hybrid approach:
A cassette toilet for daily use,
A portable toilet for emergencies or guests,
Drop toilets when available at bush camps or parks.
Others combine a composting toilet with a small urine-only cassette for more flexible liquid disposal in urban areas. Think of your system as part of a broader travel strategy, not just a single device.
Free Camp vs Holiday Park Strategy
If you’re camping in holiday parks often, you’ll have access to proper amenities and dump points, so a cassette toilet is often all you need.
If you’re aiming to free camp as much as possible, a composting toilet will offer more independence and reduce reliance on fixed infrastructure.
Many free camps now list “self-contained vehicles only” in their conditions, so travelling with no toilet system can severely limit your camping options.
No matter which system you use, proper setup and preparation will allow you to focus on the good stuff—sunsets, beaches, bush walks, and the wide open road.
Conclusion
Choosing the right toilet system for your RV is more than a matter of comfort—it’s about aligning with your travel lifestyle, respecting Australia’s natural environment, and meeting legal expectations as you move across different regions.
Cassette toilets remain the go-to for short-term trips and urban travel, offering simplicity and compatibility with widespread dump points. Composting toilets, on the other hand, empower long-term and off-grid travellers with a low-impact, low-maintenance solution—ideal for those who value sustainability and autonomy. Drop toilets serve a valuable role in many remote campsites, but they shouldn’t be relied upon exclusively.
By understanding how each system works and what suits your kind of adventure, you can avoid unnecessary stress on the road. You’ll also contribute to cleaner campsites, safer environments, and a more enjoyable RV experience for yourself and others.
Whether you’re touring the East Coast in a campervan or free camping through the red dirt heart of Australia, having the right toilet setup can make all the difference. Do your research, know your route, and prepare with the right gear—and you’ll be ready for anything.
