Hi Superchicken
As a matter of my own interest I checked into your statement and actually found this on the ATO website (link below). So I think EFY selling can occur right up until the last day of trade for that FY.

Sale or disposal of assetSelling or disposing of an asset will trigger a CGT event and you may have a capital gain or capital loss.If there is a contract of sale, the CGT event happens when you enter into the contract. For example, if you sell a house, the CGT event happens on the date of the contract, not when you settle.If there is no contract of sale, the CGT event is usually when you stop being the asset's owner. For example, if you sell shares, the CGT event happens on the date of sale.

Happy to be corrected
