A330s can park on 39 or 40, so long as the next door bay (38/35) had Ejet or smaller.
Bit more strategy required, but, barring breakdowns, the first 2 won't see each other and the first 4 won't meet except in Perth.
Still would like to know the when/where for the hangar (note spelling) and new gates. The SACL master plan looks a lot different to the existing airport.
