Oceania ↗Oceania's island states guard their farms and reefs at the border: tick 'yes' on the arrival card for any food, plant, animal product, soil or used outdoor gear, and let the officer decide.
Oceania ↗Across the tropical South Pacific, cyclones are possible from November to April: choose insurance that covers weather delays and keep one spare night before a long-haul departure.
Australia and New Zealand ↗Both countries drive on the left, with long distances between fuel stops in the outback and on New Zealand's back roads; fatigue causes more visitor crashes than speed.
Australia ↗Almost every visitor needs a visa or an electronic authorisation (ETA or eVisitor, depending on passport) before boarding: apply only through the official Department of Home Affairs site or the official AustralianETA app, and check the rules for your passport.
Australia ↗Declare all food, plant material, seeds, wood and animal products on your arrival declaration; undeclared items can bring on-the-spot fines or visa cancellation. When unsure, declare it.
Australia ↗Drive on the left. An overseas licence in English (or with an official translation or International Driving Permit) is accepted for visitors; check the state rules and your rental contract.
Australia ↗Swim between the red and yellow flags on patrolled beaches; rip currents cause most beach drownings.
Queensland ↗Marine stinger season runs November to May in tropical waters; swim inside stinger nets or in a protective suit.
Queensland ↗Queensland keeps UTC+10 all year — no daylight saving. Clocks go back an hour crossing from New South Wales in summer.

The reef runs about 2,300 km along the Queensland coast, so there is no single gateway. The reef sits closest to shore in the north, near Cape Tribulation, which makes Cairns and Port Douglas the shortest boat rides; the Whitsundays and Townsville add island and wreck options. Choose one base, book one outer-reef trip, and treat the rest as islands or coast.

Plan the nights

How to split the nights, day-trips and what to do with your bags

Open Plan the nightsClose Plan the nights3 partsNights · Day-trips · Bags

Night sequences

3 nights: Cairns 3: one outer-reef day trip, one island day, one rainforest day
5 nights: Port Douglas 3 + Cairns 2, or Cairns 2 + liveaboard 2 nights

Box jellyfish occur near beaches and river mouths north of 1770 from October to April; most reef snorkelling is outside stinger habitat, but follow operator advice and stinger suits.
The Queensland sun burns unprotected skin in about 20 minutes; sunscreen, a hat and water are not optional.
Outer-reef trips are cancelled when sea conditions are poor; the Yongala wreck is unprotected and cancels often.

Day-trips door to door

To	From	Door-to-door p50	Last return	Note
Green Island	Cairns	60 min	unknown	Half day; catamaran from Cairns, about 45 min each way.
Fitzroy Island	Cairns	50 min	unknown	Fringing reef off the beach; ferry about 45 min.
Magnetic Island	Townsville	30 min	unknown	Ferry about 20 min; koalas and snorkel beaches.

Bags between cities

Liveaboards store bags on board; day boats have limited dry storage, so travel light and leave the rest at your hotel.
