Australia, Oceania

2,300 kilometres of reef. Some of it is still extraordinary.

You put your face in the water and the noise of the boat disappears. Below, a coral garden in colours that have no business existing: parrotfish grinding away at staghorn coral, a reef shark doing slow laps, a turtle ignoring you completely. The Great Barrier Reef is 2,300km of ocean ecosystem seen mostly from the surface, which is both humbling and, in the bleached sections, quietly devastating.

Our honest take

Go to the outer reef, not the inner. Coral bleaching has hit the inshore sections hard, and a day trip to the inner reef can be genuinely disappointing. Divers get significantly more than snorkellers. Liveaboards reach the remote ribbon reefs where the reef still looks like a nature documentary. Budget trips cut corners on site selection.

Why go

  • Outer reef liveaboards from Cairns reach Cod Hole and the Ribbon Reefs, where potato cod the size of labradors swim up to inspect you at arm's length
  • Whitehaven Beach in the Whitsundays is silica sand so fine it squeaks underfoot, and the swirling tidal flats at Hill Inlet are unlike anything else on the coast
  • Lady Elliot Island sits at the southern tip of the reef with manta rays year-round and nesting turtles from November to March, no day-tripper crowds

Skip if you can

  • Inner reef day trips from Cairns marketed at budget travellers: Green Island and Fitzroy Island have heavily degraded coral from bleaching events, warm water, and too many boats. You may come away underwhelmed.
  • Seastar cruises that promise the reef in 20 minutes from Airlie Beach. The Whitsundays are islands, not reef. Know which one you're buying.
  • Semi-submarine tours marketed as reef experiences: watching coral through a scratched porthole is not the same thing as being in the water.

Where locals eat

Barramundi and reef seafood$$

Australia's iconic native fish, 'barra', grilled or battered, plus mud crab and prawns, is the reliable order along the Queensland reef coast.

Prawn Star, eaten on a converted trawler at Cairns Marlin Marina, or Dundees on the Cairns waterfront

Fresh prawns and mud crab$$$

Queensland prawns and mud crab (often chilli or salt-and-pepper) are a tropical-coast highlight, best from a marina seafood spot.

Tropical fruit (mango, lychee)$

Far North Queensland's tropical climate grows superb mango and exotic fruit, sold at markets and roadside stands in season.

Barbecue and a cold beer$$

The honest coastal-Queensland meal: a seafood or snag barbecue with a cold beer after a day on the water. Casual, not fussy.

Where to stay

Cairns city centre$-$$

Best base for outer reef and liveaboard departures, full range of accommodation, loud at night on the Esplanade

Port Douglas$$-$$$

45 minutes north of Cairns, quieter, slightly upmarket, closer to Mossman Gorge and Daintree, good reef operators

Hamilton Island (Whitsundays)$$$

Resort island with reef access, expensive and convenient, more package-holiday than adventure travel

Good to know

  • Box jellyfish and Irukandji are present in nearshore waters October to May. Wear a full stinger suit. Most operators provide them.
  • Sun exposure on the water is severe. SPF50+, shirt, hat. Reef-safe sunscreen only (zinc-based) to protect coral.
  • Cyclone season runs November to April. Travel insurance with cancellation cover is essential.
  • Decompression sickness is a real risk on multi-dive days. Follow your dive master's advice on surface intervals and depth limits.
