Tricky question Andrew but. still thinking about closer spots.
Have you thought about kipping on the boat a little off shore?
You might find a spot or two in here https://www.msq.qld.gov.au/-/media/M...acon.pdf?la=en
Teerk Rook Ra (Peel Island) National Park, Brisbane
“Where on earth is it?” is the question that often follows any mention of this hidden national park off the coast of Brisbane. This gem of a campsite on Peel Island in Moreton Bay feels a million miles from the city.
You need to be creative to get there, but if you can commandeer a kayak or boat and make for Horseshoe Bay on the southern side of the island you’re almost certain to have the entire place to yourself.
Wind-sculpted sandstone rocks, remnants of the old quarantine station and a sheltered campsite greet you. Peel Island is all about being in harmony with the world around you. Take in all the nature as turtles, dolphins and dugongs welcome you to their home.
How to get there: With no public transport you’ll need to find your own way across Moreton Bay from Brisbane or Dunwich on North Stradbroke Island. It’s so close you could almost swim there! You’ll need to book your campsite here.
