Communication from the federation yesterday explaining the season going forward..
This weekends bye is now being rescheduled with last rounds fixtures. Unlikely they will go ahead though with lockdown extension immanent, which means those games will result in 0-0.
The final series has been pushed back a week with the grand final weekend now 19th September.
From my understanding, if no further regular season games are played, the top 4 will remain as is in each grade.
Semi finals may end up being just one leg if lockdowns continue and if it comes to it, the grand final could just be first v second.

Everything is still up in the air, but it looks like every chance will be given for the season to continue.
