Prince William of Wales and Kate Middleton will possibly have their honeymoon in Lizard Island, on the Great Barrier Reef in Australia.
Lizard Island is a National Park and a collection island in the Coral Sea.
The island was discovered and named by Captain Cook in 1770.
The Island can be reached via flight from Cairns.
After the wedding, they are expected to stay in Buckingham Palace before heading to Balmoral in Scotland on Saturday.
