That's funny I was just looking at the VIC registration.
From their website there appears to be an option to become fully registered if you can meet their standards.
The High School branch of the school I am going to offers the VCE in connection with a Victorian School. (I'm primary)
The primary follows the Aust Curric. with an IB framework.
VIC looks like it may be my best bet and failing that, a year in Oz is not so bad.
Cheers
