About this site
Milln Reef sits on the outer Great Barrier Reef off Cairns, Queensland, one of a number of ribbon reefs commonly visited on day trips from that coast. The area offers a mix of coral bommies and shallower gardens typical of this section of the outer reef system, reached by boat from Cairns or Palm Cove. It is rated a beginner dive, making it a common choice for day-trip operators taking divers of all experience levels out to the outer reef.
