Welcome Smeggy! Monkey thinks you're a troll (someone who goes around adding bits to forums to wind up the posters....) but I think you're genuine - too much detail area wise not to be real.
Have you had it re-valued?
Have a look on rightmove, and see what similar properties are going for. Then knock a bit off. We're probably not the right people to ask, as we'll all say that you need to knock a lot off the price to get it sold - and we could well be right. There are 2 scenarios when the market is going down - 1) chase the market down by cutting your price bit by bit as the market goes down, or 2) start off low, and if it doesn't sell, keep knocking the price down.
There's a thread in the anecdotals section
this one - Honest EA, is as the name would suggest an EA, but not from round here, and Mildura is an EA too, there's a conveyancer or two who also set the scene on that thread too - well worth a look. Page 5, post 63, Honest EA says:

current policy is to recommend a 10% reduction every 3 weeks until it sells.
You have to bear in mind though that, presuming that you're going to buy another property to move into, that property should be cheaper too, so unless you've MEWed (remortgaged and taken the extra equity from your house out and spent it on a holiday or something) or bought recently, you haven't got much to worry about.
Good luck, and keep us posted!
