Voters were clearly impressed with Frank Carbone's leadership during the COVID-19 pandemic and responded at the polling booths on Saturday.
The current independent mayor, who won the 2016 election in a recount with a 50.15 per cent margin, has 73.8 per cent of the almost 50,000 votes (about 40 per cent) counted.
Labor's George Barcha has 26.2 per cent of the vote in the two-candidate race.
It will be Mr Carbone's third stint as mayor.
"I'm humbled by the community support for me and my team," Mr Carbone told the Champion.
"I think there was a clear message on Saturday: the community wants us to continue to invest in making Fairfield a great place and we will do that.
"They have put their trust in us and we will always fight for Fairfield."
Mr Carbone's independent team polled well at Saturday's local council elections which had been postponed twice because of the pandemic.
He is likely to be joined by three members of his group C team - Reni Barkho, Hugo Morvillo and Michael Mijatovic - in the Parks Ward with almost 43 per cent of the votes counted.
Mr Barcha looks also set to join the Parks Ward as a councillor with incumbents Andrew Rohan from the Dai Le ticket and Labor's Ninos Khoshaba and a fourth member of Mr Carbone's ticket Marie Saliba battling for the final two spots.
In the restructured Fairfield/Cabravale Ward, Charlie Saliba and Dai Le's independent tickets and Labor's Carmen Lazar's Labor ticket look likely to secure two seats each on council with 30 per cent of the votes counted.
Independent Basim Shamaon needed to bridge a five per cent gap when counting resumed on Monday.
The informal vote across both wards was very high. Postal votes are being accepted until December 17.
