If you’re thinking of heading up to Queensland there are some great beachside campsites in and around the Sunshine Coast you should check out.
Double Island Point is one of my favourite beach camping spots and great for 4WD. It’s located just south of Rainbow Beach and you can drive up to it along the beach from Noosa North Shore. There is also Freshwater campground just off the beach about 8km south of Double Island or there is Inskip Point further north.
Noosa North Shore Retreat has a great family campsite although it’s not located right on the beach (it took us about 20 minutes to walk it). Its great for the kids with a games room and swimming pool and you can drive your 4WD right onto the beach. It’s also in a fantastic location if you want to head into Noosa for the day or if you want to do daytrips such as Australia Zoo, The Eumundi markets, underwater world, Rainbow Beach or even Fraser Island.
Fraser Island will be busy around the Christmas period but if you’re looking to camp by the beach then you’ll find it’s fairly busy wherever you go around that time.
For a more central location Coolum Beach and Cotton Tree Caravan Parks are both fantastic beachside campsites on the Sunshine Coast however neither of these requires 4WD.
Hope this help with a few ideas.
