thanks guys, will check out the link you provided definitely.
Well, no exact plans for Fraser island, just though of some "sea-sun-sand" day on the island. We definitely do not plan to stay here longer as we are heading to Brisbane and further down to Gold Coast and then to Byron Bay in the next days so it will be just a hop-on/off tour just spending a day in each locations before flying back to SYD ex Ballina.
We also plan to use buses/trains all along the way between Hervey Bay (or nearest station) to Brisbane and then Gold Coast and then Byron Bay so hope we can somehow hop on and off on any buses/trains all along the way as - obviously flying from one place to the other is not too economical..
