If you have to put down 10% then you may like to consider arranging a deposit bond.
A Deposit Bond is used in lieu of cash for a deposit on the purchase of a property. The bond gives the Vendor security that can be converted to cash in the event the purchaser does not proceed with settlement of the property
If your 10% deposit is tied up in the form of shares or equity that you do not want to use yet you can leave your deposit where it is and for a premium that is lower than current bank interest rate earnings you can purchase a Deposit Bond.

Interstar will do a lo doc loan without an ABN. As you said you are unemployed this would suit you.
You can set up this type of loan by declaring that you are a full time investor ( no need for employment history/checks )
The maximum LVR that you would be able to do in this situation is 65%.
The interest rate would be in the mid 7s ( don’t know the figure off the top of my head! )
Hope this helps.
