Australia's east coast is home to many scuba diving spots, offering everything from shipwrecks, colorful corals, and shark-filled caves to watching the underwater ballet of fur seals.

During humpback whale migration season (May to November), these giants of the deep can often be spotted at various locations. Seeing them and hearing their song adds an extra special touch to scuba dives on the east coast. Here's where to see the best underwater life along the east coast.

Dive Safety Tips

  • Avoid touching any marine life. It may be dangerous, and the ocean ecosystem has many delicate corals and other organisms which can be crushed by touching.

  • Always dive within your certification limits.

  • Never skimp on the surface interval between dives.

  • Never dive in an area you are unfamiliar with, alone or with a buddy. Always go with a certified and licensed operator staffed with experienced guides who know what the potential risks are at the dive site, e.g. strong currents. Always dive with a buddy or in a group.
