those two are the main two in victoria. you can go from one to the other by heli-link for like..$99 i think it is.
buller is good for day trips, but its not as high up as the other two, and you get a shitload of tourists up there. also, at the wrong time of year you can hit the victorian interschool championships- think a few thousand kids taking over the mountain for a week.
