Today I booked my lodging in Cairns, AUS.  I now have all my lodging booked in Australia and New Zealand.  Also this week I booked flights from Melbourne, AUS to Alice Springs, AUS, to Perth, AUS to Darwin, AUS to Cairns, AUS.  The only flights I need are Dayton, OH to Los Angeles, CA and Cairns, AUS to home.  I have found a dive boat to take me to scuba dive The Great Barrier Reef, the Tusa Dive T6.
