Cr Mack has been mayor for two years, but has decided not to chase a third term even though he would be guaranteed of retaining the position if he wanted to stay on.

His decision to step aside on September 28 could spark a Melbourne Cup field of potential replacements including Alice Glachan, Daryl Betteridge, David Thurley and Henk van de Ven.

Deputy mayor Ross Jackson is out of contention as he also confirmed he would be stepping down from his post.

The replacement mayor and deputy mayor will steer the council through the final 12 months before local government elections are due next year.

Also looming on the horizon is the latest attempt at NSW council reforms with an independent review panel pushing for a merger between Albury and Greater Hume.

Cr Mack said he had taken great pride in being mayor.

"It is a commitment that I have taken very seriously and it has required a lot of personal resilience, endeavour and energy," he said.

"Essentially I took a two-year leave of absence from work so I could give my best to this role and now it is time to focus that time and energy on my family and work.

"I look forward to continuing to serve our community as a councillor and I am extremely proud of what this councillor group have achieved during my term as mayor.

"There will be a seamless transition to whoever becomes the new mayor."

Among his highlights as mayor were Albury hosting NRL, AFL, Super Rugby and A-League soccer matches.
