Hate to be that guy, but I think Gym Direct has cut prices since you bought this, as the total cost on their website at the moment is $1593 + shipping...with the 10% ausbb discount it's close to $1.4k...that's using the links you supplied to the gear.
Only because I'm currently in the market for a similar setup, and have been spending a lot of time on Gym Direct to put a package together.
Sorry and best of luck selling! If I lived in Sydney I'd certainly be keen to have a look, at least.
