Council administrator Peter Stephenson said staff were deeply saddened by the loss of Mr Thomson, a valued and respected member of the Audit and Risk Committee and a former councillor.
“On behalf of the Strathbogie community, we extend our heartfelt condolences to Alistair’s family and friends,” he said.
“His knowledge, experience and dedication have made a significant and lasting impact on the Strathbogie community.”
During his time as a councillor, Mr Thomson was involved in many decisions, projects and initiatives with roles on various committees, including environment and sustainability development, planning and audit and risk.
After leaving council at the end of his term, he joined the Audit and Risk Committee as an independent community member.
“Working alongside Alistair on the Audit and Risk Committee was a privilege,” Mr Stephenson said.
“His contributions, expertise, kindness and unwavering commitment to good governance and to putting the interests of the community first have left a lasting legacy for Strathbogie.
“He will be greatly missed.”
Chief executive Julie Salomon echoed the sentiments of Mr Stephenson and said Mr Thomson’s kindness, wisdom and inquiring mind would be sorely missed.
The mayor and councillors from when Mr Thomson served as a councillor also extended their condolences to his family and friends.
“He was an extraordinary councillor and represented the community with passion, good governance and integrity,” they said.
Vale, Alistair Thomson.
