Put Steve Irwin on the Australian currency

It's about time we payed our respects to the all time greatest Australian bloke, Steve Irwin. Let's make a change for something in the history of our country. It's been ten years without the Aussie icon and although he's been recognised in many ways I'd imagine we could all support the idea of going one step further (well deserved). With a list a mile long of all the good Steve had accomplished in our world let's show our appreciation to a great true blue Australian by putting Stephen 'Steve' Irwin on our country's currency.
Only everyone's support can make this happen!
