Also look at Capital Gain implications. Read the attached ATO guide that specifically mentions shares received "for free" e.g. like AMP did years ago.
Page 6, New Terms.
"While we have used the word ‘bought’ rather than ‘acquired’ in some of our examples, you may have acquired your shares or units without paying for them (for example, as a gift or through an inheritance or through the demutualisation of an insurance company such as AMP, IOF or NRMA, or a demerger such as the demerger of BHP Steel Ltd (now known as BlueScope) from BHP Billiton Limited). If you acquired shares or units in any of these ways, you may be subject to capital gains tax (CGT) when you sell them or
another CGT event happens.
Similarly, we sometimes refer to ‘selling’ shares or units although you may have disposed of them in some other way (for example, giving them away or transferring them to someone else). All of these methods of disposal are
CGT events."
