Stretching over 1,400 miles along Australia's northeast coast, the Great Barrier Reef is the planet's largest coral reef system and one of its most iconic natural wonders. From the legendary SS Yongala wreck to Cod Hole's massive potato cod, the diversity of dive experiences is unmatched in sheer scale. Though bleaching events have impacted some areas, the outer reefs and ribbon reefs still deliver world-class diving.
