At this time of the year the East Australian Current brings down warm water from the Barrier Reef and with it come a plethora of juvenile and some adult tropical fish, coral larvae, turtles and much more.
The EAC typically eddies over a magnificently large area to the east of Sydney, often pushing tropical fish beyond Narooma to the south. Currently at 28 degrees in the warmest areas out in the ocean, the waters closer to Sydney’s shores usually get to 23-4 degrees at this time of year.
Once here the EAC passengers find a suitable habitat and establish themselves. However, as the waters cool, towards winter the majority die off when water temperatures drop below 20 degrees, leaving only a few of the most hardy behind to wait for the next years arrival.
