Where/when: Bondi Beach, Sydney: January
Fancy yourself as a bit of a beach bum? Then join 10,000 other exhibitionists and flash your rude bits on Bondi Beach.
Freakiness factor: High - If you think this is a danger-free way to admire fit Aussie women in the buff - think again. Entering Australian waters at night leaves you wide open to a shark attack. Ouch!
