I've also been very happy with Pacific Flight Services (ex Rod-Crane) at bankstown. No affiliation, just borrowed their aeroplanes on occasion. I haven't flown with Schofields.
If you go to this address:
Airservices Australia - Flying Guides & Publications - Visual Guides - Flying Around
and launch the thingy, you can have a look at the chart. 1500 round the harbour, then not above 500ft down the coast.
