Well with the franking credits, it could go above $28.25, although in past experience it doesn't go up much further - maybe 1-2% and I wouldn't expect that until quite close to Implemention Date - which they have stated to be mid/late April 2023. More often than not, these dates get extended (even when things seem to be going well). So I would bank on say 30th April 23.
The franking credits might suit SMSF, you only get $26.50 cash, so maybe you get a tax loss as well that can be offset with future gains? not entire clearly about that. And the Dividend is FF.
Not necessarily in this case, but I've also seen very late last minute bids come in just when you thought its as all done and dusted.
