Im with Grumpy, a few hours each way...Ive had mowers sent as from as far as WA (Im in Sydney).
Know a bloke who will bring like size Items for an even 50, so its worth it in most cases.
Ive travelled to melbourne to pickup, but made a trip of it.
But....How far would I go? For A Billy Cart, Fan or even a first 100 serial Roto, I'd get on a plane to anywhere to view its Authenticity.
