Some cool stuff to do in Queenstown if you get down that far? Make sure you experience a jet boat somewhere. I'm so jealous dude. Best place in the world! Caves at Waitomo are fucking amazing, go dig a hole at Hotwater beach, do bungy jumps, raft some rapids, climb Mount Doom, hire canoes, drink Montieths Radler beer and smoke bush weed! Friendliest folk I've met, you'll have a blast mate!
