As for the trim lines (altise, sportive, etc), I can;t help because ours here are different in the US. As for the Gen's, they are the style of the Camry. Here in the US, Gen 1 is 83-86, Gen 2 87-91, Gen 3 92-96, Gen 4 97-01, Gen 5 02-06, Gen 6 07-11. Some of those years are 1 year off for you guys in Australia.
