Turning PPOR into IP

Hi I need some help/advice on my situation:

My company is relocating me from Brisbane to Perth in about 2-3months time. I have 1 property, PPOR a 3br townhouse (50/50 wife) and the loan is 3.5years old – principle & interest with redraw facility. Originally borrowed 190k (property cost 215), then 1 year later used equity and borrowed another 20 to buy a car. 2 years later the 20 was paid off. We now owe about 165k and the property would be valued around 300k. The current redraw facility is around 25k.

Current aim is to rent out PPOR, and initially rent in Perth for first 6months then consider buying a place. The plan is to turn PPOR into IP for indefinate period, probably unlikely to ever move back in. I imagine the property will be negatively geared for at least the first 5 years.

So question:
As PPOR isn’t becoming IP until 2-3 months time, can I between now and then clear out the redraw facility (leaving 1-2k) into a personal high interest account? What would be the tax consequences? Obviously I would like the IP loan to be as high as possible to keep the most amount of interest deductible, whilst taking out my excess funds – to use on a deposit for a new place.

My reasoning is that a redraw facility really means this is how much ahead of the minimum repayments you are. I understand once becomes IP, then there can be no redrawing of such money unless it is for investment purposes, or you lose the deductibility. ie. redraw personal money now, then leave mortgage alone, and only make minimum payments thereafter.

Any help/advice is much appreciated.
