Moreton Island is apparently the world's second largest sand island.

According to ourbrisbane.com...

"Moreton is 95% national park, with development restricted to just three small villages and a resort. A natural playground, it features crystal-clear creeks and lagoons, tall sand dunes, abundant wildflowers, an historic lighthouse and miles of pristine beaches. It's famous as one of only a handful of places in the world where you can hand feed dolphins in the wild at Tangalooma Wild Dolphin Resort.

For those seeking a natural island idyll close to Brisbane, Moreton is the perfect escape, offering leisure activities like swimming, snorkelling, fishing, sand tobogganing, bushwalking, dolphin and whale watching."

Tangalooma Resort has it's own site at http://www.tangalooma.com/
