Trip to Australia.

blue mountains rock! it's fun to say Katoomba.
tasmania is cool in the winter: few tourists.
west coast is tops, coral bay is beautiful... Ningaloo reef access from the beach (the turquoise water and white sand paradise kind); along with whale sharks there's big manta rays and dugongs too; dolphins down south at Monkey Mia (where there are no monkeys), and the stromatolites (abiotic or not?) in hypersaline clean Hamelin Pool’s pretty cool, too.
