hahah i did it at Picton... 20 mins from liverpool on the Hume Hwy (m5) it on the way to canberra...
cost me $308 to do tandem....next jump (tandem) is $215 and the one after is a bit cheaper still. But if you do a course you can jump by yourself. The course is 9 stages and total costs is approx $1500( that includes 9 jumps) but you can still do your first jump by yourself with your own parachute with 2 instructors either side of you
oh and it was 14000ft when i went.
and as for the getting married bit.. umm not anytime soon.. i think anyway...
