You may need to use a VPN like tunnelbear or Hola to purchase the game and get the discount, I used tunnelbear so please correct me if I'm wrong. I got the games activated on my steam account fine so please comment if something went wrong. PayPal is accepted as well so this site is fine. If you need help or something goes wrong please tell me.
Not available to Australian people unfortunately, you can purchase it (with vpn) but you wont be able to play it.
Edit : Paypal don't accept purchases using VPN anymore, if the paypal address is in Australia, it wont accept russian or brazillan currency purchases.
