Parts of Wolli Creek are flooded as heavy rain continues with the Cooks River breaking its banks at Cahill Park near the Rowers Club.
Arncliffe Street near Wolli Creek Woolworths was under water with police changing traffic conditions to two-way to allow motorists to avoid the flooding.
There were reports that the basement carpark of the Linc building was flooding with residents warned to get their valuables out.
"One resident wrote on the Wolli Creek Facebook site: "It has risen over an inch and a half since lunch time, so with rain forecast until at least the 25th - let's hope our all cars don't float away. My main worry is why none of the drains are working. The one that sits next to my car is at least 2 metres deep, is completely full and not draining."
And earlier today power was lost at almost 3000 homes in Bexley and Bexley North.
A large gum tree had fallen at the corner Bryant and George Streets, Rockdale bringing down power lines.
