Port Douglas and Cairns
Reef day sailing from two marinas an hour apart, with different reef access from each.
Port Douglas and Cairns are the two northern reef gateways, and the charter offer from each is mostly day sailing to the outer reef or the inshore islands rather than multi-day cruising.
The difference that matters is which reef you reach. From Port Douglas the Low Isles are close enough for a half day; from Cairns the Green Island and Michaelmas Cay runs are the standard. Both are inside the Great Barrier Reef Marine Park, so the operator's permit and the zoning of the site decide where you may actually anchor and snorkel, not the brochure.
Both towns are in the tropical north, which means the wet season and cyclone season shape availability far more than demand does. May to October is the reliable window.
