The other alternative to explore with your tax agent is a move to a status of share trading as a business with the ATO, where you would deduct the value of your 30 June shareholdings as "inventory".

However I understand that this is very complicated and I don't know the ins and outs and how much you need to be trading to qualify (and how easy it is to change back, you lose CGT discount under this status I think), worth asking your tax agent if it is an option.
