I am doing BMid at Monash. It is offered down at the frankston (peninsula) campus. They also offer the double degree down at gippsland.
Other Uni's in melb are ACU, Vic uni? and latrobe i think has the double degree. I think Deakin also offer the double degree at Geelong and Burwood. (not 100% sure on that one though)

You need to apply through Vtac- www.vtac.edu.au

Also, for those thinking of UNISA external mid is not going to be offered to people from different states from the 2011 intake, as it is too hard for them to find placements outside of SA.
