It looks likely that nine of the 11 Queanbeyan-Palerang councillors have been decided but it may be several days before the full council is confirmed.
There were 40,665 enrolled voters heading into the council election and an electoral commission spokesman said that all first preference votes should be accounted for by midday on Tuesday.
As of Monday, 29,788 votes had been counted with Mr Overall's independent team collecting 34.7 per cent of the first preference vote and likely winning four seats on the new council.
That means Mr Overall, Trudy Taylor, former deputy mayor Peter Bray and newcomer Michele Biscotti are all on track for a place at the table.
On Saturday night as votes trickled in Mr Overall said he viewed the positive results as vindication for his performance as administrator.
The huge support for the Overall team had the ticket earn two-and-a-half times more first preference votes than second-placed Country Labor, as of Monday recording 13.5 per cent. Former Palerang councillor Trevor Hick’s ticket was next earning 9.63 per cent, then the Liberal Party on 9.15 per cent.
Independent and former councillor Kenrick Winchester’s ticket picked up 9 per cent of first preference votes.
The Greens' ticket is just shy of a full quota, with 6.45 per cent of first preference votes, but there is a chance the party will win a seat with the highest proportion of a full quota as of Monday.
That would mean Peter Marshall takes a place at the council.
A spokesman for the New South Wales Electoral Commission said that with results as they are, voters could be fairly confident with those nine council seats.
The remaining two seats will take several days to finalise as preferences are allocated.
At the time of writing the informal vote count stood at 9.85 per cent and voter turn out at 73 per cent of enrolled persons.
If those numbers held steady it would be a similar result to the 2012 council elections.
Queanbeyan and Palerang both returned an informal count of 9 per cent in 2012.
However, the electoral commission spokesman said that the informal vote could change substantially as votes are data entered in the coming days as some votes will in fact be found to be formal.
He said people voting both above and below the line was common and the worst kind of informal voting.
Queanbeyan recorded a 76 per cent voter turn out in 2012, while Palerang had an 82 per cent turn out.
