I agree with Scott, it looks most like a Southern Water Skink (Eulamprus tympanum) and yes it looks gravid.
It's certainly not E. quoyii because there is no indication of a pale dorso-lateral stripe, which is characteristic of this species and it's out of range.
At first I thought it was E. heatwolei because of the strong yellow colouration of the belly but after closer examination I can see that it has a pale anterior margin to its ear-opening, rather than a black anterior margin, which is a key difference between these two species.
