I would allow 3 days . It is 1220k Brisbane to Wagga . I would go either Warwick or Toowoomba then to Goondiwindi then follow the Newel to Wyalong , then turn left just past the Shell roadhouse to Temora to Wagga . Apart from between Coona and Gil mainly flat running .
Hi buffy61, I originally came from near Wagga. There are several van parks to chose from The Wagga Beach Van park down on the River which would be the oldest park in town. We stayed there a long time ago when the kids were little, nice shaded park. Then there is the big 4 stayed there last year and would be the pick out of the two for me if you wanted long term. Also Forest Hill has a park, I would not stay there very run down. Then if you did not want to stay in wagga Junee has a lovely park and is about 40 k's away. You also have the choice of free camping on the river at Wilkes Park, North wagga for a few days until you made up your mind which park you would like to stay at. Anyway enjoy wagga a great City with heaps of things to do and see.
Its a small world, we also lived many years in Wagga, but its the coast for us now. agree with all that Copper1 said re caravan parks, cheers Capricorn
