Hello, I am from Norway and I'm visiting Australia this November. I have been in Australia before when i was a kid. And i remember the very good water slides from when i was a kid. Me and my brother would like to try some fun water slides when we are in Australia again. I remember especially well that we tried a lot of fun "tunnel slides" (i don't know if that is their real name). Our trip will start in Sydney, go to Canberra, Benalla, and then Melbourne. Are there any good parks with exiting slides somewhere on this route? The main one oIhave found after doing some searching is Manly Waterworks, is this the best alternative? Seems like the best ones are on the gold coast, but that is to far away from our route.
