You can get _closer_ to positive gearing by either reducing your ongoing costs and/or increasing your income. 

Reducing costs can include:

1. Performing maintenance yourself (obviously where legal to do so!)
2. Not using a real estate agent (see my signature below) for property management
3. Correctly claim any depreciation allowances available

Increasing your income can include:

1. Increase rent.  Can be justified by providing new/upgraded facilities (ie reno)
2. Subdivision, leading to more rent 

Of course, once you've sorted these out, you would apply to the Tax office for a ITWV (Income Tax Withholding Variation) so you receive the benefits of your negative gearing immediately, rather than end-of-year.
