The trouble is, while the ASX trades at a discount to the AIM, Australian shareholderswill then be able to sell into the AIM market at a profit
I fully expect the sp on the AIM to take a hit ahead of this as AIM holders sell out in anticipation

On the AIM there is no restriction on the amount of shares issued for a fund raise, so there is potential for substantial dilution if required
