My friend did this recently to get pass these new turbo, V8 rules. I think he said he only had to be a resident for 3 months in SA. Once the 3 months went by, he went to SA to get his licence. The next day he came back to Melb and drove. He's now living in Melb, but he is still 'living' in SA.
What he told the cops when he first got pulled over was that he was trying to sell the car and they let him off. He told me if he knew the trouble to get his licence in SA, he wouldn't have done it. He gets to drive a turbo car on his Ps so I think it would've been worth it.
