OK, here's the sad truth, not guesswork from people living interstate.
One of our members lives in Werribee and he says there is no hope of seeing any of the objects you name from Werribee.
The only one you 'might' see is NGC253 when it is at Zenith on a clear night away from as much light as possible. But probably not.
Otherwise, go for a drive out of town and they will become visible.
