I've thought about this in the past when I've had to move bikes long distances after buying something and finding that the commercial freight rates were high. (Quoted $377 today for Sydney to Grafton !!!!!!!! $586 Adelaide to Grafton). Maybe there are ADV people who will move a bike for petrol money - say $100/200 for this distance. I'm facing a 4000 km return drive to Adelaide to pick up a recent buy and would gladly pay someone to bring it even to Sydney. So the idea would be that you'd just list your capacity to cart a bike, or your need to get one shifted here. Obviously it's not going to be Express service.
