We are a family of 5, children under 7 and are planing a trip with our pop up caravan from Melbourne to Noosa for 5 weeks in the end of Dec through Jan. We plan on heading to Surfers on the Hume hwy but are taking out time coming back along the coast. We plan on staying 6 night in surfers and unsure about 5 nights in Noosa or Hervey Bay (somewhere nice around there). Heading back were planning Sydney and Blue mountains, Jervis Bay, Merimbula, Port Macquarie Lakes Entrance. Is there any places that anyone can recommend or replace with the ones I've mentioned. We mainly like some nice beaches suitable for children. We also wanted to stay in Coffs Harbour but they have a 5 night min stay which we aren't planing to stay there that long so if anyone can recommend a town outside of Coffs Harbour? Thanks in advance for your help.
