Yes, this is a possible way. You can claim potential rental income to your actual income. But you need to be sure the address you use to sign the contract and applying the loan is different to the actual property. This trick can usually be done by a good broker, it is a little risky, but if you are desperating to get the property, this is a reasonable solution.
BTW, you can still claim your first home grant and stamp duty concession. Just tell your solicitor you are buying it as first home and you will self occupy it.
