The A-League grand final is locked in for June 26 while the competition is still hopeful premiers Melbourne City will be able to host finals despite Victoria's COVID-19 outbreak.
The top six teams are already locked in but only top-placed City and second-placed Sydney FC have secured their position - including a week off, then a home semi-final.
This weekend's games will decide who finishes between third and sixth between Brisbane, Central Coast, Macarthur FC and Adelaide United, and therefore the make-up of the two elimination finals.
City are entitled to host their semi-final on June 18, and if they progress the grand final, with the league hoping to keep things that way pending the state of Melbourne's lockdown.
Currently games in Melbourne can only be played behind closed doors.
"It is our intent to play the Melbourne City FC-hosted A-League 2021 semi-final at AAMI Park in Melbourne, however we will confirm the venue nearer the time, pending COVID restrictions in place at the time in Victoria," the Australian Professional Leagues said in a statement.
"Sydney FC's A-League 2021 semi-final will be hosted at Netstrata Jubilee Stadium."
City's game against Newcastle at AAMI Park that was postponed due to Melbourne's coronavirus outbreak still needs to be completed before finals.
The game is expected to be played as a mid-week fixture next week but the date and venue are yet to be locked in.
