Go see a mortgage lender or your bank manager and ask would be my suggestion. It may have a bit to do with what they value the house you're buying at and what price you're paying too
Do you have anyone that would be in a position to be a guarantour.? With a very generous MIL doing ours we got our house on a 100% loan, so there's always other options. (yes you do have to pay the mortgage insurance etc, but otherwise we couldn't have bought our house and are now in a position of having equity in our home and have re-mortgaged without the MIL's help) So we only had enough money to cover the solicitors and searches etc ( a couple of grand from memory)
Also in QLD we didn't have to pay stamp duty as first home buyers (that was 6 years ago though), so check that out too.
