NSW's booked-out beach campgrounds: Trial Bay to Seal Rocks

Drive the Pacific Highway from South West Rocks down to Forster and you pass some of the most contested campsites in Australia. Trial Bay Gaol, Hat Head, Diamond Head, Crowdy Gap, Mungo Brush, The Ruins, Seal Rocks. Every one of them books out for every school holiday period, and most summer weekends besides.

Here's the thing that trips people up: these campgrounds are spread across five different national parks, and one of the famous names isn't a national park campground at all. But almost all of them sit on the same NSW National Parks booking system, which means one set of rules and one strategy covers the whole circuit. This guide goes camp by camp, then covers the strategy.

How the NSW rolling window works

NSW National Parks doesn't do release days. There's no ballot, no waiting room, no 7am scramble. Bookings run on a rolling window through the RezExpert platform: new dates open as the window advances, and how far ahead you can book varies by campground. Some popular campgrounds take bookings up to a year out.

That sounds relaxed. It isn't. It just moves the competition from one morning to every morning. The campers who get Boxing Day at Trial Bay are the ones who knew when their dates would enter the window and booked that day. For school holidays, sites go within days of appearing. For long weekends, sometimes hours.

On refunds, know two things. Under the current terms, cancelling 31 days or more before arrival returns 75% of your camping fees, cancelling any later returns 50%, and the 2.5% booking fee is never refunded. And a shake-up is coming: NSW has proposed scrapping the booking fee, simplifying site pricing, and moving refunds to a 3-day threshold with up to 80% back. The consultation closed in May 2025 and the final rules haven't been published yet, so check the terms when you book. More on why the refund tiers matter at the end.

Trial Bay Gaol, behind the beach at South West Rocks

The one with the 19th-century prison ruin at the end of the beach. Trial Bay Gaol campground in Arakoon National Park has 91 sites, powered and unpowered, right behind the beach at South West Rocks. Maximum 6 people per site, check-in from 2pm.

It's the biggest drawcard on this list and behaves like it. School holiday dates go as soon as the window opens, and summer weekends aren't far behind. If you're chasing a cancellation here, you can set an alert for Trial Bay Gaol rather than refreshing the page.

Hungry Gate, the quiet one at Hat Head

Hat Head National Park has two campgrounds: Hungry Gate, at the southern end of the park, and Smoky Cape near the lighthouse. Hungry Gate is the better known of the two, an unpowered campground about a ten-minute walk from the beach.

The searches for "hat head camping" dwarf the actual supply here, which is exactly why it books out. Both campgrounds run on the same NSW Parks window as everything else on this list.

Diamond Head and the Crowdy Bay camps

Crowdy Bay National Park, on the coast near Port Macquarie and Taree, has four campgrounds: Diamond Head, Indian Head, Kylies Beach and Crowdy Gap. Diamond Head is the headline act, a big open campground behind the beach under the headland. The kangaroos grazing between the tents are enough of a fixture that they're in NSW Parks' own photos of the campground.

Diamond Head takes the school-holiday hit first. Indian Head and Kylies Beach are the quieter fallbacks a few minutes away, and Crowdy Gap is the small one down the southern end. If Diamond Head is booked out for your dates, check the other three before giving up on the park. An alert on Diamond Head covers the wait.

Mungo Brush, Yagon and the Myall Lakes depth chart

Myall Lakes is the volume player: 21 campgrounds spread between the lakes and the coast. Mungo Brush is the flagship, in the Bombah Broadwater precinct at the park's southern end, sitting between the water and the beach about 20km up Mungo Brush Road from Hawks Nest. It's the one that fills first, and you can set an alert for Mungo Brush when it does.

Yagon, tucked behind the dunes near Submarine Beach at the park's northern end, is the wilder option: unpowered, no showers, no water supply at all. When you get it, it's one of the best beach camps in the state. Bring everything. The rest of the 21 are your depth chart. When the coastal camps are booked out, check the lakeside spots like Violet Hill and Korsmans Landing before you write the park off.

The Ruins on the Booti Booti peninsula

Booti Booti National Park runs along an 8km peninsula between Wallis Lake and the ocean, and The Ruins is its one campground, at Seven Mile Beach about 15km south of Forster. Close enough to town for coffee and fish and chips, far enough to feel like camping. Forster's holiday population multiplies in school holidays and The Ruins books out with it.

Seal Rocks: the one that isn't NSW Parks

Seal Rocks pulls more camping searches than almost anything else on this coast, and it's the trap. The campground at the village, Reflections Seal Rocks, is run by Reflections Holiday Parks, a NSW Crown land operator with its own booking site, its own pricing and its own cancellation rules. Booking it through the national parks site isn't possible, because it isn't a national park campground.

For national park camping near Seal Rocks there's Yagon, just outside the village off Seal Rocks Road in Myall Lakes National Park. So decide which experience you're after: holiday-park camping at the village, booked through Reflections, or an unpowered national park site at Yagon on the standard NSW Parks window.

One alert strategy for the whole circuit

Because six of these seven names share one booking system, the strategy is the same everywhere:

1. Know your window. Count back from your arrival date: school-holiday dates enter the booking window months ahead, and the good camps go within days of opening. If your dates are still months out, set a reminder and book the morning they appear.
2. Have a second camp in the same park. Diamond Head full? Kylies Beach. Mungo Brush full? Violet Hill. The famous name books out long before the park does.
3. Watch for cancellations instead of refreshing. NSW Parks documents no waitlist anywhere in its booking terms. In practice a cancelled site just reappears on the booking page for whoever happens to be looking. The refund tiers also make cancellations somewhat predictable. The 75% tier expires 31 days before arrival, so speculative bookings tend to get cancelled around that mark. A second wave comes from people who decide later that half a refund beats a wasted weekend.

That last part is the gap Schnerp fills. We watch NSW National Parks campgrounds, including this whole circuit, and send an alert the moment a booked-out date opens up. Set your dates once and let the refreshing happen automatically.

If your spring school-holiday plans are already looking booked out, the window for the September and October dates has been open for months. Cancellations are the realistic play from here, and they do come. The 31-day refund deadline for a late-September arrival lands in late August, which makes the next few weeks exactly when speculative bookings get released.

The full story on the refund rules, including the overhaul NSW has proposed but not yet switched on, is in the NSW cancellations and refunds guide.
