I had ROGUE up in the Northern Territory .. personalised plates were only $150 up here. Just got the ones they handed me when i came back to Queensland.
I have one that says "ORBIT". Ohio was over $100 to renew. That's tire or performance mod $$$$ so I went with the next sequential OH plate and hung that one on the wall with some of my other old biker memories.
At about $500 a year in New South Wales I passed up the oppportunity.
Saw a great Chaser episode where they went around handing out "wanker plate" infringement notices to young guys in hotted up yobbo mobiles with personalised plates.
You can see my Queensland plate, I was very lucky to purchase it from the guy who ordered it 6 months before the Rockets were released in Australia.
They cost about $2500 now.
