mate, go do some mountain flying with the wakatipu aeroclub in queenstown. Its very serious countryside, dont go down there solo in a rented 152! go for a ride with a local C cat first (=grade 3) first. A completely un-australian experience, you'll love it. You can fly around all day down there with nothing but snow and rocks out the windscreen, and above you. Franz Josef and Fox Glaciers are well worth the mission, some great mountain valley passes out of q town to get out there too. Best flying in NZ I reckon, have fun!
