There may have been some querying between ASX and BIG last week over a day or two before the issuing of the Aware Letter. That would explain some delay, but I agree, if the Aware Letter was received late last week then don't you burn the midnight oil through the weekend to have a response vetted and ready to go today?
Hopefully a response this afternoon and this doesn't linger on.
