Claiming stamp duty

Hi all,
My wife and I bought a land and house package in the A.C.T as a investment property, the house will be completed by the end of the year.
We have to pay $8,500 stamp duty, what we would like to ask is,how do we claim to stamp duty (in our tax return?) and how much would we expect to get back? as we are first timers to investing.
Your help would be appercated,
Isn't the ACT different?

In the ACT you don't actually buy a property, rather you lease it, and this somehow affects the way stamp duty can be claimed, but I'm not sure how

I thought you could no longer claim stamp duty on leased property, either, as of a couple of years ago.
This might have been a good question to have asked BEFORE buying the property?
