shouldn't be much of a problem, as it's already registered just make sure you have the papers from original owner / dealer, but not forget to insure it from the day you bring it home,
We purchased interstate (new) as it was unregistered we towed home with 28 day permit from Vic Roads, we toured Philip Is. and NSW South coast on the way home.
As ours was unregistered we did require a Blue Slip, as it was over 2 ton with Break-away system it Blue Slip had to be done by a Heavy Vehicle inspector, though I didn't require a weigh bridge ticket as it was on the compliance plate, they just checked dimensions chassis and vin numbers, made sure lights and break away was working correctly.
