Vague estimates don’t help anyone. “It depends” is technically true but practically useless when you’re trying to decide whether you can afford to leave. This guide breaks down what Big Lappers actually spend, week by week, category by category, across three budget levels. The numbers come from real travellers, not marketing brochures, and they reflect the messy reality of buying overpriced fuel in Broome, paying $55 for a powered site in Byron Bay, and discovering that a “quick shop” in a remote IGA costs twice what you’d pay at Woolworths.
Your numbers will be different from these. Every trip is unique. But these benchmarks give you a realistic starting point to build your own budget, rather than guessing and hoping for the best.
The difference between a successful Big Lap and a financial disaster is tracking your weekly spend from day one.
The Real Numbers: Three Budget Levels
These are weekly averages for a couple travelling in a caravan. Family budgets are covered separately below each category.
| Category | Tight | Moderate | Comfortable |
|---|---|---|---|
| Accommodation | $0–$70 | $100–$250 | $250–$450 |
| Fuel | $100–$160 | $150–$250 | $200–$350 |
| Food & Groceries | $100–$150 | $150–$250 | $200–$350 |
| Activities | $0–$30 | $30–$100 | $80–$200 |
| Miscellaneous | $30–$60 | $50–$100 | $80–$150 |
| Total Weekly | $500–$700 | $800–$1,200 | $1,200–$1,800 |
Tight budget ($500 to $700/week average): Mostly free camping, cooking every meal, limited paid activities, careful fuel planning. Entirely doable but requires discipline and willingness to skip some experiences. This is not roughing it; it’s smart travel with good planning.
Moderate budget ($800 to $1,200/week average): Mix of free camping and caravan parks (roughly 50/50), eating out once or twice a week, some paid activities, less fuel stress. The sweet spot for most couples who want comfort without excess.
Comfortable budget ($1,200 to $1,800/week average): Mostly caravan parks, regular dining out, paid tours and activities, premium fuel choices. A comfortable pace without watching every dollar. Common among retirees with stable super income.
Families: Add 30 to 50% to the couple figures. A family of four on a moderate budget typically spends $1,100 to $1,600/week. Kids increase food costs, often push you toward caravan parks (playgrounds, pools, facilities), and paid activities multiply.
Accommodation
Accommodation is the single biggest variable in your weekly budget and the area where your choices have the most impact.
Free camping: $0. Council reserves, rest areas, station stays, and bush camps that cost nothing. Quality ranges from spectacular riverside spots to gravel patches beside a highway. WikiCamps is essential for finding them. Free camping is the foundation of budget Big Lap travel.
Low-cost camping: $5 to $20/night. National park campgrounds, some council campgrounds, and basic private camps. Usually no power but often include toilets and sometimes water. National park passes ($30 to $150/year per state) reduce the per-night cost significantly.
Caravan parks: $35 to $90+/night. Powered sites with access to amenities: showers, laundry, camp kitchen, sometimes a pool. Prices vary wildly by location and season. Peak season in popular areas (Byron Bay, Noosa, Broome) can hit $90+/night. Off-season in smaller towns is $35 to $45.
The budget lever is your split. A couple doing 5 nights free and 2 nights in a park averages $70 to $130/week. A couple doing 7 nights in parks spends $245 to $630/week. That single decision is the difference between a $600/week trip and a $1,200/week trip.
Five free nights and two powered nights keeps you comfortable without breaking the budget. Seven powered nights doubles your weekly spend.
Fuel
Fuel is the second-largest expense and the least negotiable. You have to move the van, and the van is heavy.
What to expect: Most tow vehicles consume 14 to 22L/100km while towing, depending on the vehicle, the van’s weight, terrain, and speed. At $2.00/L diesel (a reasonable national average, though remote areas can hit $2.50+), a vehicle doing 16L/100km and 400km/week spends $128/week on fuel. At 600km/week and 20L/100km, that’s $240/week.
The remote premium: Fuel in remote areas (outback NT, WA north of Geraldton, western SA, Cape York) typically costs 20 to 50 cents more per litre than capital cities. On a 30,000km trip, that premium adds $600 to $1,500 to your total fuel bill.
How to save: Slow down (dropping from 110 to 95km/h saves 10 to 15% on consumption), use fuel apps to find the cheapest prices, fill up before remote stretches, and use loyalty programs (Woolworths Everyday Rewards, Coles Flybuys linked to Shell). Small savings compound over 30,000km.
Food & Groceries
Food is the third-largest expense and the one with the most room for creativity.
Cooking at the van: A couple cooking every meal from the van kitchen spends $100 to $180/week on groceries, depending on dietary preferences and whether they stock up at major centres or buy from small-town shops. Meal planning and batch cooking bring costs to the lower end.
Eating out: A pub meal for two costs $40 to $70. A café breakfast is $25 to $40. Fish and chips by the water is $20 to $30. Once or twice a week adds $40 to $100 to the weekly food budget. Every night adds $280 to $490.
Grocery prices in regional and remote Australia are 20 to 40% higher than capital cities. An IGA in a small outback town charges more because freight costs more. Stock up at Woolworths or Coles in major centres and top up locally.
Families: Kids eat constantly. A family of four typically spends $200 to $350/week on food, more if teenagers are involved. Snacks, school lunch equivalents, and the inevitable “can we get an ice cream?” add up faster than you’d expect.
$8 for bread, $12 for milk, $45 for a roast. Regional grocery prices hurt, but you pay for convenience and freight costs.
Activities & Entertainment
Australia is full of free things to do: beaches, national parks, walking trails, wildlife, fishing, swimming holes, sunsets. On a tight budget, you can fill every day without spending a cent. But some paid experiences are worth every dollar, and skipping everything to save money defeats the purpose of the trip.
Free activities: Most of your daily entertainment. Beaches, bush walks, fishing, snorkelling (if you have your own gear), wildlife spotting, stargazing, exploring towns, playgrounds for kids. These are often the best parts of the trip.
Paid activities ($20 to $100/person): Museum entry, guided tours, wildlife parks, boat trips, cultural experiences. Budget $30 to $100/week if you want to do one paid activity a week. More for families.
Premium experiences ($100 to $300+/person): Scenic flights, multi-day tours, diving, fishing charters. These are the bucket-list items. Budget for 2 to 4 over the entire trip and treat them as planned splurges rather than impulse decisions.
Everything Else
The “miscellaneous” category is where budgets leak without anyone noticing.
Phone and data: $50 to $100/month. Your Telstra plan. Add Starlink at $139 to $180/month if you use it. This is a fixed cost regardless of budget level.
Gas bottle refills: $20 to $35 per 9kg bottle. How often depends on usage: cooking-only users refill every 3 to 6 weeks. Users with gas hot water and heating refill every 1 to 3 weeks.
Laundry: $5 to $15/load. Laundromat costs at caravan parks or in town. Once or twice a week for a couple. More for families. A caravan washing machine saves money over a long trip but adds weight and uses water and power.
Vehicle consumables: $10 to $30/week averaged. Windscreen washer fluid, oil top-ups, light globes, tyre pressure checks, minor repairs. Small and irregular but they add up over 12 months.
Personal and toiletries: $10 to $20/week. Sunscreen (you’ll go through a lot), insect repellent, toiletries, medications, and the occasional replacement item (thongs, hat, sunnies).
The surprise costs. A tyre puncture repair ($20 to $50), a broken awning arm ($200 to $500), a vet visit for the dog ($150 to $500), a speeding fine ($200+), a lost fishing rod ($100). These aren’t weekly costs but they happen on every Big Lap. Budget $50 to $100/week as a miscellaneous buffer and be grateful when you don’t spend it.
- Weekly spend for a couple: $500 to $700 (tight), $800 to $1,200 (moderate), $1,200 to $1,800 (comfortable). Families add 30 to 50%.
- Accommodation is the biggest lever: 5 free nights + 2 park nights averages $70 to $130/week. Seven park nights averages $245 to $630/week.
- Fuel costs $100 to $350/week depending on distance, vehicle efficiency, and fuel prices. Remote areas add a 20 to 50 cent/L premium.
- Food costs $100 to $350/week. Cooking at the van keeps costs low. Regional groceries are 20 to 40% more expensive than capital cities.
- Miscellaneous costs ($50 to $150/week) are where budgets leak: gas, laundry, phone, consumables, and surprise repairs add up invisibly.
- Track your actual spending from week one. Your real numbers will differ from these benchmarks, and adjusting early prevents blowouts later.
