Australia Bookings: The Places and Permits You Must Book Ahead (2027)

Australia is mostly a turn-up-and-go country, but a few of its headline experiences are not. From the Overland Track to BridgeClimb and the Field of Light, the best dates sell out early, and the whole trip needs a visa before you fly. Here is what to book, where, and how far ahead.

Which places in Australia need booking ahead?

Most of Australia runs on spontaneity, but a handful of its best experiences have strict daily limits, mostly to protect fragile tracks, reefs and sacred places, or simply because spots are few. If you have not booked the Overland Track in summer or a K'gari permit, no booking means no start.

Booking windows differ, so set reminders as soon as your dates are fixed.

How do you book the Overland Track?

The 65 km Overland Track from Cradle Mountain to Lake St Clair is Tasmania's classic walk, and from 1 October to 31 May every independent walker must book a start date. Only 34 can start each day, and bookings for 2026/27 opened on 7 July 2026 through a virtual queue.

• Fees: the summer fee is A$312 per adult and A$272 for children and concessions, and you also need a valid Tasmanian parks pass.
• One way only: in season you walk north to south, usually over six days.
• Winter: from June to September there is no booking fee or start limit, but walkers must still register online and carry a valid parks pass, and should expect snow at any time.

Last season more than 3,000 walkers confirmed bookings within six hours, so be online early.

How far ahead should you book BridgeClimb Sydney?

BridgeClimb takes small groups over the arches of the Sydney Harbour Bridge from The Rocks. Day and night climbs run most of the year, but dawn climbs are limited and sell out first, then twilight. Book as soon as your Sydney dates are fixed.

• Climbs: the Summit (3 hours, 1,332 steps), the Ultimate, and the Burrawa Climb with a First Nations storyteller.
• Who can climb: minimum age 8 and height 1.2 m; over-75s need a GP certificate.
• Cost: on the 2025–26 rate card an adult Summit day climb was A$364 midweek and A$374 at weekends, with a A$30 surcharge from 25 December to 4 January.
• Rules: everyone is breath-tested and must be under 0.05; phones and cameras go in lockers.

If you miss the slot you wanted, night climbs often have more space and were the cheapest on the 2025–26 rates. Prices change each year, so check the current rate card before you book. Climbs go ahead in light rain but can be paused in storms, and your whole group must arrive on time for the safety briefing.

Do you need tickets for a Sydney Opera House tour?

Only if you want to go inside. The forecourt and steps are free to wander, but the Sydney Opera House Tour, which takes you into the main venues, needs a ticket. Tours run daily, last about an hour and are booked on the Opera House website.

The standard tour is in English, with separate tours in French, German, Spanish, Japanese, Korean and Mandarin, which run less often. Book these ahead, as each departure has a limited group size.

The tour covers up to 2.5 km and about 300 stairs with no lift, so it is not for everyone. To see a show instead, book through the Opera House directly; popular nights sell out weeks out.

How do you book Uluru and the Field of Light?

Seeing Uluru at dawn is a Northern Territory rite of passage, and everyone entering Uluru-Kata Tjuta National Park needs a park pass. It costs A$38 per adult for three days or A$50 for a year, and under-18s are free. Buy it online from Parks Australia and save it to your phone.

• Field of Light: Bruce Munro's 50,000-plus lights, booked through Ayers Rock Resort.
• Tours: sunrise, sunset and cultural tours from Yulara fill fastest in the cooler months.
• Beds: almost all rooms near the park are at Ayers Rock Resort, so book a bed before your tours.

The climb closed permanently on 26 October 2019, so plan around the base walk instead. In the hotter months start early: on days forecast to reach 36°C or more, the Valley of the Winds at Kata Tjuta closes beyond Karu Lookout from 11am.

Do you need a permit for K'gari?

Yes, if you are driving. Both K'gari permits are bought online, before you go.

A vehicle access permit is required for every vehicle driving on K'gari, the world's largest sand island, off the Fraser Coast. Buy it online in advance and check the number plate details are right, because you must show a printed or digital copy if a ranger asks. Only high-clearance 4WDs suit the sand tracks, and the barge is booked separately with the ferry operator, so line up both before you leave the mainland.

Camping permits are needed at every campground and beach camping zone, including fenced areas such as Wongai and One Tree. Advance bookings are required for holiday periods. Wongari (dingo) rearing season runs 1 September to 30 November 2026, and some sites have booking limits then.

Should you book a Great Barrier Reef trip in advance?

Usually, yes. Day trips to the outer reef from Cairns, Port Douglas and the Queensland Whitsundays run on boats with fixed numbers, and in school holidays the popular ones can fill several days ahead. Overnight trips, island stays and liveaboards have far fewer places, so book those as early as you can.

Your ticket usually includes the Reef Authority's environmental management charge, which the operator collects for every visitor: A$8 a person for a full day or A$4 for a part day at the latest published rate. It helps pay for managing the Marine Park.

Leave a spare day in your plans, as reef trips can be cancelled in strong winds or rough seas, especially in the trade-wind months. Our guide to Great Barrier Reef snorkelling and diving covers where to go.

Do you need an ETA or eVisitor to visit Australia?

Yes: almost every visitor needs a visa before flying. Eligible passport holders, such as Americans and Canadians, apply for an Electronic Travel Authority (ETA) in the official AustralianETA app, for an AUD 20 service charge. Many European passport holders can instead apply online for a free eVisitor. Both allow stays of up to three months each visit, over 12 months.

Home Affairs advises against locking in travel until your visa is granted. On arrival, declare all food, plant material and animal products on your incoming passenger card; false declarations can bring fines of up to A$6,260.

What can you do if a booking is sold out?

• Check for cancellations: sold-out dates on most booking systems free up as other travellers change plans, especially in the final weeks.
• Try another session: BridgeClimb runs from dawn until night.
• Use a tour: K'gari 4WD tours handle the vehicle permit and barge for you, and Uluru tour companies include transfers from Yulara.
• Change season: the Overland Track needs only registration from June to September, though winter walking suits experienced, well-equipped hikers.

Fees and rules change often, usually once a year. Always confirm on the official booking page in the week before you go.
