theres a few good ones in Aus..
ALmost nothing in the world compares to parks like mammoth, whistler, snowparknz etc..
Our parks might have 4-5 jumps and anywhere from 5-25 jibs, nothing TOO big though.
Falls Creek, Victoria is probably the best park in Australia.
They are pretty creative, e.g Last season they had a school bus which you could jib.
In New South Wales, Perisher + Thredbo arent too bad, provided there is snow.
