of the mass produced type rides there are quite a few options...
all the surlys and the salsa casserole are available in aus through dirtworks. most bike shops can order through them.
you could go an on-one il pompino through definitive cycles (just google easy to find, nice quick service, $60 postage!) - i am in the process of getting one for my winter ride.
pake or soma rush are easy to get in aus.
masi, kona and the cannondale whatever they are called are also available.
bianchi pistas are common too, as are hillbricks which can be set up for ss with the back brake deal.
racelines are around too.
