There's some other decent sized sites further North after you come out from the bypass track heading to Bulwer also. We stayed about a klm North of where that bypass track hits the beach (at the Northern end) when we did our trip there with the guys from 4WDA magazine. Our campsite had their 3 vehicles aswell as about half a dozen of our guys vehicles set up in the one site, some were in tents and some rooftopping in their vehicles, and one person had a camper trailer set up in there aswell. I can't recall what our site number was though sorry to say. If you all have camper trailers it won't be big enough though, if the others are in tents then no worries. I don't recall alot of large sites up where we were, i more recall us having one of the larger sites, but my memory is hazy of what's there as it was our first time on Moreton in many many many years.
