with most countries including all of Europe shipping a frame is easy with USPS. it's fairly cheap too. maybe about $65. it's much more expensive with Fedex or UPS but at least they have tracking (not that USPS has ever lost anything of mine). shipping a bike is possible but very difficult with USPS. the box must be 108" (length plus girth). it can be hard to cram a bike in a box that small.
now, as far as Australia goes.....your up against a wall. shippers really dont like going there. USPS will not ship anything large there. Fedex is the cheapest for a bike is like $450. keep your trasactions with that corner of the world limited to very small items.
