Mr Ierino tendered his resignation, effective from February next year, saying the decision had not been an easy one.
“Serving as CEO of Indigo Shire Council has been one of the greatest privileges of my professional career, and I will always be grateful for the confidence that successive Councils have placed in me,” he said.
“After considerable reflection, I have reached the point in my career where the time feels right to move on from full-time executive leadership in local government.
“I am looking forward to a different chapter, one that provides greater flexibility while still allowing me to continue to contribute to the sector.”
Mr Ierino said he would be leaving the role with a strong sense of pride in what had been achieved during his tenure.
“Council has faced many challenges and opportunities, and I believe we have consistently approached them with integrity, professionalism and a genuine commitment to serving the Indigo community,” he said.
“None of those achievements would have been possible without the support of dedicated councillors, an outstanding executive leadership team, and the many talented and committed staff who serve our community each day.”
Mayor Sophie Price said it was with a heavy heart that Council had accepted Mr Ierino's resignation.
“Trevor has led the organisation with steady hands and a genuine care for our communities for almost nine years, and on behalf of Council I want to thank him for his dedication, his integrity and the enormous contribution he has made to Indigo Shire,” Cr Price said.
“This is a well-earned next chapter, and while we will miss him, we are grateful for the strong foundation he leaves us to build on.”
She said Mr Ierino was committed to an orderly transition over the coming months and would continue to lead the organisation with the same energy and professionalism that had guided his approach over the past nine years.
