BEST DAY TRIP BY BOAT FROM BRISBANE: MORETON ISLAND Just 40 kilometres from Brisbane is the picture-perfect Moreton Island. This offshore gem is the third largest sand-island and home to some pretty steep dunes, like Mount Tempest. But don’t be mistaken, there’s more than just sand here. Spend the day snorkelling among the island’s famous shipwreck and tropical fish, hire a kayak, or check out Moreton Island’s slice of war history. Getting there is easy – simply hop on a ferry, boat or barge.
