I think with that result you can go to almost any foundation program there.Why you want to go there straight?Go do SAM or something in Taylor's or Ausmat in Sunway or something first before heading to Australia =)

What kind of art are you interested in?A lot of Art Degrees can be entered by taking no matter what subject in Pre-U.So my advice is do a pre-u here and choose subjects that you are very confident you can score so you can get into uni as art degrees don't usually have pre-requisites. Or if you have the money nobody can stop you =) choose a very good uni and take their foundation to be sure you can enter their degree.If you want to go straight to Australia I would recommend you to go and discuss your options with IDP.They give the best advice on going to Aussie to further your studies ^^
