Autumn
Scuba Diving in Australia in April
Arguably the best all-round diving month in the country.
April is many Australian divers' favourite month. The tropics are out of the wet season, the east coast still holds summer warmth, and the crowds have gone.
Ningaloo's whale shark season is running, Great Barrier Reef visibility is typically excellent, and southern temperate sites are still comfortable before winter sets in.
It is also the month when temperate macro diving starts improving as water clarity picks up.
Ningaloo & ExmouthWhale shark season in full swing, with settled conditions.
CairnsDry season beginning — reliable reef visibility and calmer seas.
Townsville, Ayr & the SS YongalaImproving conditions for the SS Yongala as the wet eases.
Newcastle, Nelson Bay & Port StephensFly Point macro diving improving as inshore water clears.
