Things to Do in Great Barrier Reef

The Great Barrier Reef unspools like a living mosaic off Queensland's coast, coral gardens pulsing with electric-blue parrotfish while the sea changes from glass-green to cobalt in a blink. Salt spray settles on your lips as you drift above bommies that click with feeding surgeonfish; a sudden cool updraft announces a manta ray sliding under your kayak. At dusk the reef edge smells of ozone and grilled barramundi drifting from nearby cays, and night brings the soft slap of waves against pontoons plus the distant thrum of dive-compressors winding down. Surface from a dive and a sea turtle may be staring at you like an old neighbour; island bars plate lime-tart coral trout burgers while fruit bats flap overhead like ragged umbrellas.

Cairns' Night Owl markets (Wednesday-Friday) smoke up ginger-lime bugs and chilli mud crab on outdoor woks; join the queue at the Singaporean stall near the lagoon steps for peppery laksa thicker than most you'll find in Sydney. In Port Douglas, grab a coral trout taco from the lime-green truck outside the surf club—mid-range for the town but half what waterfront restaurants charge for the same fish. Airlie's main drag hides a shabby Vietnamese joint where locals swear by the barramundi pho; the broth arrives steaming with lemongrass so fragrant it drowns out boat-fuel smells drifting up the street. Overnight on Hamilton and slip into the yacht-club bistro before six for half-price tapas while crews argue over mooring fees and kookaburras swipe leftover calamari rings.

April through early June delivers glass-off mornings, calm ferry rides and water warm enough to skip the wetsuit—though stinger suits are still advised off Cairns. July and August bring whales and crisp 25-degree days, but trade winds can chop the outer reef and some live-aboards cancel moorings when south-easters top 25 knots. November turns hot and sticky; coral spawning converts night dives into underwater snowstorms yet summer jellyfish bloom means stinger nets go back in and some beaches close by midday.
