If you do wish to persue the consignment options, then as Dale mentioned would be worth talking to Jacksons. While you are in Annandale also have a chat to the guys at Global Vintage, depending on what they have they may or may not be interested, but they will tell you up front one way or another. I used them to sell an amp for me back when they first set up and was pretty happy with how it all went.
The other guy who floats abit below the radar is Matt from
http://www.mattsvintageguitars.com/. Although he does not have a shopfront, seems he has a bit of a network of buyers, looking at his site at the moment he seems to have a few of the non tele/strat type fenders, so may be worth a chat. He has been around for a while and used to work at Jacksons for quite a while.
Finally, wild horse guitars in surrey hills would be worth having a chat to also. They do seem to have a some vintage guitars amonght their stuff. They have always been helpful without trying to sell me anything the few times I have been in there, although I have not used them to sell or buy anything.
Cheers
