It's a credit to Australia that most of it's tourists must be looking for fun, adrenalin, crazy and unusual entertainment, adventures and activities. This can be seen from the high percentage of our things to do in Australia which can be fairly considered as 'unusual activities'!
You can take your choice from numerous operators in most of these categories!
Jetskiing, Jetboating and high thrill speedboat rides in Australia
Hot air balloon flights in Australia
Skydiving in Australia
Australian Trike Tours
Oz Kayak Tours - including a heli kayaking opportunity of course!
Australian motor sports activities
Extreme flights over Australia
Horse riding in Australia
Then there's the more 'one off' activities which look great. Things like:
Karaoke Shopping Tours of Sydney - maybe a bit of Abba on board ;-)
Horseback Wine Tours - what could possibly go wrong!
The Nullabor Links - The World's Longest Golf Course at 1365km - yes that's KM - if playing it is not unusual enough for you take a trike tour of the Nullabor!
Great White Shark diving, Crocodile diving or the slightly more rare Tuna diving (very poor pun intended!)
Heli kayaking, biking and whale watching (these three are done seperately - that would be unusual!), stretched jeep tours, croc tours and many many more!
