Eldo, I'm 'Adelaide based' too. Given the car's age, a lot can change in registration requirements and also this car's engine specs in the last 20 plus years since it was first registered. I would suggest speaking to a good compliance engineer who can advise you easily whether you're looking at an easy run or a minefield. Then you know what to expect.
Can recommend one if you want to do that.
Cheers,
Glen
