3,680,000 plus your usual fob tax will be about $46,000AUD to buy. Then add 5% duty on top which equals $48,300, then add 10% gst which is then $53,130, then add about $1500 freight, then $2000 for compliance, then another $1000 for misc stuff, so what's that, about $57,630.
If the car needs tyres than add that as well, plus the usual registration and transfer costs. So I would say, about $60k on road.
