"I do agree though that if you are travelling Adelaide to Canberra you wouldn't go via Mt Gambier." quote
Logic would agree with you.. However being experienced in organising freight from Adelaide to Canberra.. very little of it goes direct. Most will go via Sydney, however the majority of freight in Australia runs btw Sydney and Melbourne and if a truck is empty returning from the west via Adelaide and can pick up.. it will go East towards Melbourne ( Mt Gambier) before heading north towards NSW.
