A caravan trip around Australia can cost very different amounts depending on how far you drive, how often you stay in caravan parks, the size of your tow vehicle, your food habits and how many paid experiences you include. As a practical starting point, many couples can model a Big Lap at about $1,000 to $1,300 per week for a careful budget, $1,400 to $1,900 per week for a balanced trip, or $2,000 to $2,800+ per week for a more comfortable travel style.
Those are planning scenarios, not promises. A remote leg with long distances and expensive fuel can cost far more than a slow month with several low-cost camps. The useful question is not “What did someone else spend?” It is “What will our route, rig and travel style cost?”

What should a Big Lap budget include?
A realistic caravan travel budget needs more than fuel and caravan parks. Break the trip into separate categories so an expensive week does not hide inside a single rough figure.
- Fuel: towing fuel, sightseeing kilometres and generator fuel.
- Accommodation: caravan parks, station stays, national park camps, showgrounds, low-cost camps and occasional free camps.
- Food and household supplies: groceries, takeaway meals, restaurants, drinking water, gas refills and laundry.
- Vehicle and caravan costs: servicing, tyres, repairs, consumables and roadside assistance.
- Experiences: tours, cruises, attractions, fishing charters, park passes and local events.
- Connectivity and administration: mobile plans, satellite communications, mail, registrations and insurance.
- Health and personal spending: prescriptions, appointments, clothing and everyday personal expenses.
- Emergency reserve: money that is available without relying on a credit card limit.
Three useful weekly budget scenarios
Use these bands to start a conversation, then replace them with your own figures. They assume the tow vehicle and caravan have already been purchased and exclude finance repayments, depreciation and major pre-trip upgrades.
Careful budget: about $1,000–$1,300 per week
This generally requires slow travel, regular low-cost or free camping, mostly home-cooked meals and firm limits on paid attractions. It is more achievable with a fuel-efficient combination, good solar and battery capacity, and enough water storage to stay away from powered sites when conditions allow.
Balanced trip: about $1,400–$1,900 per week
This allows a mix of caravan parks and lower-cost camps, moderate driving, regular café or pub meals and selected tours. It gives more room for maintenance and makes it easier to change plans without the whole budget falling apart.
Comfortable trip: about $2,000–$2,800+ per week
This may include frequent powered sites, longer driving days, more paid experiences, eating out regularly and higher everyday spending. Remote tours, peak-season parks, ferries, vehicle repairs and extended stays in popular destinations can push individual weeks well beyond this range.
Tip: Do not choose the lowest band simply because it looks achievable on paper. Choose the travel style you can realistically maintain for months.
Fuel is usually the biggest moving target
Towing fuel cost depends on distance, real towing consumption and the price paid per litre. Use this formula:
Fuel cost = kilometres ÷ 100 × litres per 100 km × fuel price per litre
For example, 500 km at 18 L/100 km with fuel at $2.20 per litre would cost about $198. The same distance at 24 L/100 km would cost about $264. Over a long trip, that difference matters.
Do not build the budget from the vehicle’s highway brochure figure. Load, wind, speed, road surface, tyre pressure and the caravan’s shape can all change towing consumption. Record several real fills while towing and use the average.
Fuel prices are also volatile and can be higher in regional and remote areas. The ACCC explains the factors affecting Australian fuel prices and recommends comparing prices where practical. Add a buffer instead of assuming today’s cheapest metropolitan price will apply around the country.

Accommodation can be cheap, expensive or simply unavailable
Your average nightly cost depends on the mix of places you use. Free and donation camps can reduce the average, but they are not available everywhere and may have stay limits or few facilities. Caravan parks can provide power, water, laundry and a convenient base, but rates may rise during school holidays, events and peak seasons.
National parks and reserves may charge entry, camping or booking fees. Facilities and rules vary, and some locations require advance bookings or permits. Check the relevant state or territory authority and current park information before relying on a site. Parks Australia also notes that fees and amenities can vary between campgrounds.
A practical method is to estimate the percentage of nights you expect to spend in each type of camp. For example:
- 30% free or donation camps
- 25% national park, showground or low-cost camps
- 45% caravan parks
Multiply the number of nights in each group by a realistic nightly rate for the regions and season you plan to visit. Then add a small allowance for the nights when weather, mechanical trouble or fatigue changes the plan.
Food costs do not automatically fall when you travel
A caravan kitchen can reduce takeaway spending, but small regional supermarkets may cost more and limited storage can lead to frequent top-up shops. Include groceries, drinking water, gas, coffee stops, takeaway meals and restaurants as separate lines if you want to see where the money goes.
Before departure, look at two or three months of normal household spending. Remove expenses that will genuinely stop, then add the travel costs that will replace them. This is usually more accurate than copying another traveller’s grocery target.
Maintenance and repairs need their own reserve
A service allowance is not the same as an emergency reserve. Regular servicing, tyres, bearings, brakes, filters and consumables are predictable over enough kilometres. A damaged awning, failed fridge, suspension problem or unexpected tow-vehicle repair is not.
Keep scheduled maintenance in the weekly or monthly budget and hold emergency money separately. The appropriate amount depends on the age and condition of the vehicle and caravan, warranty coverage, remoteness and how quickly you could access other funds. Do not treat a credit card limit as the whole plan.
Paid experiences are part of the trip—not a budgeting failure
Iconic tours and local experiences are often the reason people undertake a Big Lap. If you leave them out of the budget, you may travel thousands of kilometres only to say no when you arrive.
List the experiences that matter most before departure. Estimate them individually, then add a smaller weekly allowance for unplanned attractions. This helps protect the “must do” items while giving you room to discover something new.
Do not forget the costs that continue at home
Your Big Lap budget should sit beside a home-cost plan. Depending on your situation, you may still have mortgage or rent, rates, storage, insurance, subscriptions, vehicle registration, loan repayments and property maintenance. A travel budget can look comfortable until these fixed commitments are added.
Separate the numbers into:
- One-off preparation costs before departure.
- Weekly travel costs while moving around Australia.
- Continuing home and financial commitments.
- Emergency and return-home reserves.
A worked Big Lap budget example
Consider a couple planning a 12-month trip with a balanced travel style. They expect to average:
- $330 per week for fuel
- $350 per week for camps and caravan parks
- $280 per week for food and household supplies
- $180 per week for experiences and eating out
- $120 per week for maintenance and vehicle allowances
- $140 per week for insurance, communications, health and miscellaneous costs
That produces a working travel budget of $1,400 per week, or $72,800 for 52 weeks. A 10% contingency would add $7,280, bringing the planning total to $80,080. Home commitments and pre-trip purchases would still need to be added.
This example is deliberately simple. The free calculator lets you use your own distance, fuel consumption, nights, food allowance and trip length.
How to make the trip cost less without making it miserable
- Slow down. Fewer kilometres per week can reduce fuel use and create longer-value stays.
- Travel outside peak periods. Where climate and access allow, shoulder seasons may improve availability and pricing.
- Mix accommodation types. Use paid sites for the facilities you value and suitable lower-cost camps between them.
- Plan fuel stops. Compare prices, but do not risk running low to save a few cents per litre.
- Cook most meals, not every meal. A realistic café and takeaway allowance is easier to maintain than an all-or-nothing rule.
- Track weekly. Review the rolling average rather than panicking over one expensive remote week.
- Protect the reserve. Do not quietly spend emergency money on ordinary travel.
How much contingency should you add?
A common starting point is 10% to 15% on top of the planned travel total, plus a separate emergency amount. Increase the buffer if you have an older rig, plan long remote sections, travel during uncertain weather or have limited access to income while away.
Recalculate whenever the route, trip length or fuel consumption changes. A budget is a working navigation tool, not a number you set once and ignore.
