OK, so here's your second problem. You leave Melbourne, and assuming you hug around the coast towards Adelaide, you don't have too many stopping points. You do have the option of calling in to Adelaide / Port Adelaide, then perhaps either Port Lincoln or Whyalla both of which have large and accommodating harbours (Whyalla is an iron ore mining town and it has a "working" harbour capable of taking ships of any size really). From there you have a lug across the bight, which is (a) desert and (
fringed with (in places) 100ft high cliffs, preventing any form of landfall. Even if you did need to stop there is nowhere to do it -- no towns, no ports, no river entrances, no people really, this is just a big desert.
Your next port of call is really Albany in WA. Again this has a good sized harbour and is well worth calling into, or perhaps Fremantle further around the coast. But really you need to treat the haul from Whyalla or Adelaide across the bight as an "ocean crossing" and make sure you have sufficient fuel and supplies on board to make the trip across as you can't expect to be able to stop anywhere on the coast.
Once you're heading up the WA coast to the 30 degree lat line, your ports of call are really only Fremantle (Perth) and Geraldton. Nothing north of Geraldton offers any form of refuge until you reach Port Hedland in the north west. Again this is one big red sandy desert, average annual rainfall in some places is effectively zero, so don't even expect to be able to pick up water on this leg.
