Hi, Living in whistler for couple years and not getting stoked on winter like before and since i can apply for working visa to australia, is it somewhere in aus place to do a summer season in bikepark like Thredbo or is there any different good biking spot.
Tasmania is a great bet - Maydena is the place to be, with the option of heading up north to Blue Derby for short trips to mix things up as well.
On mainland Australia, the parks are fairly small. Thredbo in NSW or Bright (Mystic + Falls) in VIC probably the best options for proper bike parks that i'm aware of.
If heading down to this part of the world, New Zealand is probably also worth a look too. Queenstown Bike Park is meant to be great, with relatively easy access to a number of other resorts nearby (Coronet Peak, Cardrona etc.).
