bruno, the best route is the one you are going to enjoy. If you are after a quick trip, Broken Hill, Sydney, Kurri Kurri and up the New England. Scenic route, follow the coast
I like Zoomtopz first suggestion. I just drove from Melbourne to the Sunshine coast. If you want to get into big city driving and freeways, from Goondiwindi, go to Warwick then the direct track to Brisbane via Ipswich Motorway, then join the Gold Coast Freeway, over the Gateway Bridge and freeway to Mooloolaba. Just another suggestion to consider...

Since light travels faster than sound, some people appear bright until you hear them speak.
