Saturday's election may represent one of the biggest shake-ups of council in many years.
At risk are two long-serving veterans in former mayor Daniel Myles and deputy mayor, Chris Van der Kley, along with the Greens' Brent Hoare and Liberals Kevin Schreiber and Brendan Christie.
Mr Myles, who resigned from the Liberal Party, contested the election as an Independent.
"Running as an Independent has been challenging but rewarding. I could not have remained as a Liberal candidate given the State Liberal Government's agendas for overdevelopment, increased heavy vehicle traffic and flooding of the National Park.
There are still five places undecided which will be determined by preferences.
In Ward 1, the third place behind Suzie van Opdorp (ALP) and Sarah Redshaw (Greens) will be taken by either Mr Schreiber or Don McGregor (ALP). Both men were members of the last council.
In Ward 2, only Romola Hollywood (ALP) has secured a spot. In the running for the other two places are her number two, Claire West, Mr Hoare, Mr Van der Kley and Jo Bromilow (Liberal).
In Ward 3, Mick Fell (ALP) and Roza Sage (Liberal) are confirmed. The final place will be contested between Mr Myles and the Greens' Kingsley Liu.
And in Ward 4, Mr Christie, a member of the last council, is vying against the third member of Mark Greenhill's team, Helen Clifford.
Ward 2's Cr-elect Hollywood said she was "bowled over" by the early result for Labor in her ward in a "competitive field".
"While we may not know the final results until around 21 December, the strength of support suggests it is possible that my running mate Claire West, a fabulous young woman who has grown up in Woodford, may also be elected. I acknowledge all the Ward 2 candidates who have worked hard ... and are also waiting on the final results."
Ms Hollywood said it was a "strong message the community was saying no to overdevelopment - people really value that we are in a city in a world heritage area".
Mr Van der Kley said Monday's counting was looking favourable for his election for a sixth term. Like Mr Myles, he also resigned from the Liberal Party to stand as an Independent. The move split the Ward 2 Liberal vote down the middle, but he was "quietly confident of being elected" and felt "very grateful".
Mr Hoare was hopeful the Greens vote would be buoyed by a high volume of iVote results due to be published late Wednesday. Liberals Ms Bromilow, Mr Christie and Mr Schreiber said they would not be commenting with so many votes to be counted. All candidates thanked their supporters.
