Purchasing property from future father-in-law

Hi all, it has been a little while since my last post.

I was hoping to get everyones thoughts on a potential opportunity that has recently arisen. My future father-in-law owns a number of properties and has recently retired so is looking to sell a couple off and one of these would be a good opportunity for me and my fiance.

I am comfortable with the due diligence that needs to be required (as I have been through the purchasing process a few times before) so what I was looking for was some advice as to the best way to proceed with the transaction, where various taxes (stamp duty for me, CGT for him etc.) can be minimised. I understand that properties can be transferred between spouses without incurring stamp duty and I was wondering if something similar can be done between parent / child?

The property is in Victoria so if there is anyone that has any experience in this, any advice would be greatly appreciated.

Thanks
