Learn to Surf!
If you move to or are even just visiting Australia it is basically a requirement for entry into the country that you at least try surfing. There are tons of surf schools throughout Australia and some really fun surf tours you can take. Last year I took a 5 day Sydney to Byron ‘Learn to Surf Trip’. It was Awesome! Even if you don’t have 5 days- most of the big beaches have local half day lessons. The equipment and clothing is provided. These are just a few links. Once you have learned- almost every little beach town has a surf shop where you can rent a board to match your ability. Hang 10 Baby!
