Only experience I've had is getting one from Mayfair ( Nino posted the link in an earlier post ) . They have a lot more glasses than they list on their site so it pays to ask .
As for postage to Australia I'm not sure if they do or not . I was lucky enough when I got mine to have it sent to Illinois Pinball and a local Aussie dealer shipped it over for me ..
I did the same. Packaging from Mayfair was excellent. The process ended up taking 6 months but the end result was exceptional.
