Shellharbour City Council has promoted from within after announcing Wayde Peterson as the new Chief Executive Officer.

He was appointed less than three months after Mike Archer was sacked following an extraordinary meeting to vote on a confidential report containing information that was "provided to Councillors concerning personnel matters".

Archer's contract was terminated - he had been on leave since the start of March following revelations that he was under investigation for inappropriate conduct at Council's Christmas Party.

Peterson had held the Acting CEO position since February after he previously served as Council’s executive director of business enterprises.

Shellharbour City Mayor Chris Homer was confident Peterson would thrive in the role.

“This is a pivotal time for Shellharbour City Council. We are setting the stage for a strong and vibrant future,” he said.

“Wayde’s leadership skills, strategic vision and genuine commitment to community will be invaluable in helping shape that future.”

Peterson began his career at Shellharbour as an engineering cadet in 2000.

The 45-year-old, who was born and raised in the Illawarra, returned for his second stint at Council in 2018.

“I’m honoured to be appointed as CEO of Shellharbour City Council,” he said.

“Council plays an important role in delivering high quality infrastructure and services that help improve the quality of life of our community.

“I am excited to partner with the Mayor, Councillors, our excellent staff and the community to deliver on the vision of a sustainable and thriving City.

“Collaboration with staff, local communities, partners and government will remain central to how I lead and the outcomes we achieve together.”

A father to two boys - Finn, 14, and Wes, 12 - he is active in the local sporting community as a junior football coach and has been a surf lifesaving volunteer for more than 30 years.
