Im an Aussie! im going there in july
In Jindabyne (town before snowy mountains) theres cheap accomodation. and it takes about 30mins to get to the snow fields. However theres HEAPS of hotels etc....in the perisher/smiggins valley. not sure about pricing though
when i went last year, Blue Cow had the BEST powder :P within the week that i was there the snow fall was awesome, best they've had for a while.
Perisher Blue: http://www.perisherblue.com.au/winter/index.php
Accomodation within Perisher Blue: Perisher Blue Holiday Accommodation, Hotels, Lodges, self-contained
and heres the place we stayed last year and were staying there again this year: Alpine Gables
the rooms are pretty good, kitchen, bathroom, awesome view (lake and mountains), balcony, bar and bistro, sauna and laundry etc....
as for hiring, heres some websites...
Ski hire, snowboard hire, snow boards, ski clothing rental, Jindabyne
Alpine Sports and Natural High Jindabyne - the Snowy Mountains premier ski & snowboard centre.
What time are you looking at going?
hope this helps!
