If they can't make Albert Park a championship round, it could free up a weekend; the calendar would have to be assembled in such a way to avoid a clash with the Grand Prix.
Sandown's days appear to be numbered, even with the recent contract extension. Another event would need to step up as the 500; I imagine Phillip Island would to keep an enduro in Victoria and the circuit has tge facilities (although I wouldn't say no to a New Zealand enduro, but might require an extension to Pukekohe or moving the round to Hampton Downs or Highlands).
QR talked up the idea of an extension, and they seemed to be pinning their future on it, but it seems to have stalled. I don't think anyone would miss the Paperclip if it fell off the calendar, even if it meant the only Queensland races were on street circuits.
If the second Bathurst circuit happens, I think they would be hard-pressed to justify four rounds in New South Wales when Queensland and Victoria only get two (assuming Sandown and QR disappear) - even if Bathurst is sacrosanct. I'm concerned that Newcastle could go the same way as Canberra and be too narrow.
