Was searching through a coffee machine replacement and found the Gaggia Classic on amazon.co.uk delivered for around $250 AUD (It came out to £163 total for me in the checkout as it removes vat but adds express shipping in it). There's some for £189 and then there's some for £169 (which you should pick if you don't mind waiting). It will take a few weeks for delivery but it is new, 220-240v compatible but you will need a power adapter to convert from UK to Aussie plugs (ebay).
Yes, I know it has aluminium boilers, but for $250, a commercial grade group head and other quality components included, I don't think you can go wrong. Apparently pulls pretty good shots too.
Im in Qld and I got - We're sorry. This item can't be shipped to your selected destination.
