Southern Great Barrier Reef, QLD
Lady Musgrave is a small uninhabited coral cay 60 km north-east of Bundaberg, ringed by a 1,200-hectare reef lagoon with a single navigable entrance. The lagoon is calm, shallow (3 to 8 m) and ideal for Open Water training and snorkelling, with the outer reef wall dropping to 25 m+ on the seaward side. Dive sites include the lagoon bommies, the western drop-off and the entrance channel where reef sharks congregate. Day-boats run from Bundaberg and 1770; multi-day liveaboards reach the cay as part of longer southern-GBR itineraries.
Visibility at Lady Musgrave Island typically ranges from 15 to 30 metres, though it shifts with swell, wind and recent rainfall. Year-round; calmest April to November generally offers the best conditions for diving here.
