If you bought at the low this year, you wouldn't have a CGT exemption, it's 100% assessable. If you have held longer than 12 months then you have booked a loss. So not sure what you are talking about.
Double brokers fees is understandable, that's why i said buy back at 2.28 and you are no worse off, assuming you are buying a decent amount.
Point is, you can be no worse off buying back in under this above scenarios, if you truly didn't want to sell.
