Frequently Asked Questions About Great Barrier Reef
QIs the Great Barrier Reef dying?
While some areas have experienced coral bleaching, the GBR is massive (2,300km) and many sections remain healthy. Remote sites accessed by liveaboard show excellent coral health and fish populations.
QDay trip or liveaboard?
Day trips from Cairns visit the outer reef and are great for beginners. Liveaboards access remote sites like Cod Hole and Ribbon Reefs for the best diving. Budget 3-7 days for liveaboards.
QCan I dive the Yongala wreck?
Yes! The SS Yongala is one of the world's best wreck dives, accessible from Townsville or Magnetic Island. Advanced Open Water recommended due to depth (15-28m) and currents.
