Seastar CruisesResort

Seastar Cruises runs a fast, air-conditioned catamaran from Cairns out to the outer Great Barrier Reef. The day starts at Michaelmas Cay, a seabird and turtle sanctuary and the largest of the uninhabited coral cays nearby, then moves on to Hastings Reef, 30 nautical miles out from Cairns.

The boat carries a maximum of 36 guests a day, with snorkeling and diving both possible and a buffet lunch onboard. On the way back it passes Oyster Reef, Upolu Cay and Green Island, reaching Cairns around 4:15pm. It is a PADI Resort, and trips are in English.
