The creatures lay eggs on dry land, mainly around Gobba Lake and Eric Singleton Bird Sanctuary, and the hatchlings make their way to the closest water.
City senior environmental field officer Yolanda Rhemrer said while most of the turtles had finished hatching for the season, there were still lots of sightings.
“They are very active this time of year – two weeks ago walking across the road at Gobba, we saw four turtles heading back to the lakes; I don’t know if they had been nesting,” she said.

Ms Rhemrer urged drivers to keep an eye out when driving in those areas and to call the Turtle Oblonga Rescue and Rehabilitation Network if an injured turtle was found.
Turtles should not be picked up unless they are injured or in danger from predators such as cars, foxes, dogs, cats, ravens and kookaburras.
Ms Rhemrer said the second spring at the restored bird sanctuary had meant plants had grown, providing nesting areas for birds and turtles.
“It’s amazing how the plants have grown in a year, all the birds that come, they have a lot of protection there – mostly purple swamp hens,” she said.
“Little dotterels nest in the mulch… it’s very camouflaged and carries its babies under its wings with its feet sticking out – it’s absolutely adorable.”
