How to plan the Big Lap in school holiday windows (without blowing the budget)

School holidays add roughly 30–40% to powered-site prices at popular parks — I've seen the same BIG4 site at Airlie Beach go from $65 a night in term time to $92 over Easter. That's before you factor in school holiday surcharges on ferries, higher fuel demand on coastal highways, and the complete absence of a powered site anywhere within cookin' distance of the Whitsundays if you haven't booked four months out. Doing the Big Lap with kids in school is completely doable, but it needs a different kind of planning than the grey nomad version.

This is the approach I've refined over two and a half laps with my two kids (now eight and eleven) and a border collie who sheds on everything. It's not about avoiding the school holidays — you literally can't. It's about making them work for you rather than against you.

Start with the school calendar, not the map

Most people plan a Big Lap by drawing a line on a map and then checking when they can leave. Flip it. Open the school term dates first — your state's Department of Education website publishes them two years in advance — and mark every holiday window on a calendar. Then layer the seasonal logic on top of that.

The reason this matters: the Big Lap has hard seasonal constraints. The Top End is inaccessible or miserable in the wet season (roughly November to April). The Nullarbor is uncomfortable in summer. The Victorian High Country and alpine areas close in winter. If your school holidays land at the wrong time for a particular leg, you're fighting both the calendar and the weather.

The good news is that a lot of Australian families doing the Big Lap take their kids out of school for extended periods — formal long-service arrangements, or enrolling with a distance education provider. If that's your plan, you have much more flexibility. But if you're working in strict holiday windows, read on.

The seasonal logic for each leg

Here's how the main legs of the lap line up with school terms, roughly speaking. I'm talking about the classic anticlockwise run (Sydney → Melbourne → Adelaide → WA coast → Darwin → Queensland → back to Sydney), which is one popular choice — though our piece on which direction to do the Big Lap covers the tradeoffs in detail.

The East Coast (Sydney to Cairns): This works in almost any school holiday, but July is the sweet spot. Warm enough in Queensland, cool enough in New South Wales, and you miss the summer crowds that clog the Whitsundays in January. Book BIG4 Adventure Whitsunday at Airlie Beach at least 10–12 weeks ahead for July school holidays — it books solid.

Queensland's interior and into the Northern Territory: The window between mid-April and the end of June is ideal. The wet season is fading, temperatures are manageable, and you've got the September–October school holidays to push through to Darwin if needed. Avoid January and February up here with a caravan unless you genuinely enjoy watching the radar.

The Kimberley and WA north coast: May to September is the only realistic window. That maps well onto the Easter holidays and the July school break, but it means you need to be in the Kimberley by mid-May at the latest for the best conditions. The Gibb River Road can still be partly closed in April some years, so check current conditions with the Shire of Derby–West Kimberley before you commit.

The Nullarbor and South Australia: March–April or September–October. Summer is brutal on the Nullarbor — I've seen ambient temps of 46°C at the Head of Bight in January. The April Easter holidays are perfect for this leg; the wildflowers on the SA coast are a bonus. Streaky Bay Foreshore Tourist Park is a great base for a couple of nights on the way through.

Where school holidays cost you the most (and where they don't)

Not all peak pricing is equal. The parks where school holiday surcharges hit hardest are coastal Queensland (anything from the Sunshine Coast to Port Douglas), the popular WA coastal parks around Exmouth and Broome, and anything near a major theme park or tourist town in New South Wales. These are also the places where availability disappears fastest.

Where school holidays barely move the needle: the outback. Remote SA, the NT interior, far western Queensland. Birdsville Caravan Park doesn't have a school holiday surcharge because the season is the season — it gets busy in the cooler months regardless. Same goes for national park campgrounds that use a permit system rather than dynamic pricing.

My general rule: budget the coastal legs generously and save money on the inland legs. In practice, our powered site costs drop by about 35% when we swing inland. That gap funds the coastal nights when we need them.

Booking strategy: what to lock in early, what to leave loose

I'll be honest — I used to resist booking too far ahead because I hate feeling locked in. But two school-holiday seasons of getting shut out of parks taught me to be more strategic about it.

Lock in early (6+ months):

• Any coastal Queensland park during July holidays
• Broome and the Kimberley coast (May to August is the entire tourist season)
• Popular SA parks over Easter
• National park campgrounds with permit systems — Parks Australia and each state's parks authority use online booking and allocations fill fast

Leave loose:

• Outback legs — you'll find a spot almost anywhere in the NT interior or western QLD with reasonable notice
• Free camps and rest areas — by definition you can't book these, and they're often your best option for breaking up the expensive coastal stretch
• Mid-week nights at smaller towns where demand is lower

Using an app like WikiCamps or Campermate (covered well in our camping apps rundown) helps you spot nearby free options if your first choice is full. I've genuinely never been stuck without somewhere to sleep — we've just occasionally ended up at a free camp that wasn't on the original itinerary, and sometimes those turn out to be the best nights of the trip.

Budgeting realistically: the school holiday premium

Based on our own records from the last two east-coast runs, here's what school holidays actually add:

Term-time average for a family powered site on the east coast: $55–$70 per night. School holiday average for the same quality parks: $75–$100 per night. Over a 14-night school holiday window, that's a difference of $280–$420 just on accommodation. Across a full Big Lap with four distinct school holiday periods, you're looking at an extra $1,000–$1,500 in site costs compared to doing the exact same route in term time.

That figure is worth building into your plan rather than being surprised by it. Our full Big Lap budget article at what a lap of Australia actually costs has a solid breakdown of overall costs — add the school holiday premium on top of those figures if you're going with kids.

One thing I'd push back on gently: the instinct to offset those costs by free camping more during the school holiday windows. Free camps near popular coastal tourist areas fill up fast and often have a 48- or 72-hour limit, which means you're moving every couple of days. With kids, that's exhausting. Spending the money to stay three or four nights in a decent park during holidays is often worth it for everyone's sanity, including yours.

Schooling on the road: the bit nobody tells you

If you're planning more than a full school term on the road, you'll need to look at distance education. Each state has its own provider — Queensland's School of Distance Education, the NSW Distance Education schools, and so on. They're legitimately good, and the kids I've met doing it are generally fine academically. The admin to enrol takes longer than you'd expect, so start that process at least two months before departure.

The practical reality: schooling takes 2–3 hours a day, which means you're not doing big drives on school days. We typically do our moving days on Fridays and weekends and use Monday to Thursday as base camp days. It's actually not a bad rhythm once you're used to it — we see more of each place because we're not just passing through.

The leg that surprises most families

Everyone talks about the Kimberley or Cape York as the hard bits. But honestly, the leg that catches most families off guard is the stretch from Darwin back down through Queensland — specifically the inland Queensland run through Mount Isa, Longreach, and down toward the coast. It's long, it's hot from October onward, and there are big gaps between decent parks.

If you're doing this leg in the September–October school holidays, plan your fuel and water carefully, give yourself extra days so you're not driving 500km in a day with two kids who've run out of podcasts, and don't underestimate how much the kids need a park with a pool or jumping pillow after four days in the outback. The slow travel piece says it better than I can — the families who struggle most on this leg are the ones trying to cover too much ground too fast.

Plan the school holiday windows as your anchor points, fill in the gaps with flexibility, and give yourself permission to stay an extra night when you find somewhere the kids (and you) actually love. That's the version of the Big Lap worth doing.
