Balli Singh has replaced former Gosnells deputy mayor Adam Hort who resigned last week.
Mayor Terresa Lynes said the council was pleased to have Cr Singh on board.
“We look forward to working with Cr Singh to represent and serve the City of Gosnells community,” she said.
The appointment of Cr Singh is in line with recent changes to the Local Government Act, which allow vacancies on council to be filled by the candidates who polled the highest and second highest number of votes without being elected at the last election.
Council will vote for a new deputy mayor at the next council meeting on Tuesday.
Ms Lynes acknowledged Mr Hort’s tireless passion for protecting the City’s wildlife.
He gained council support for the policy to enhance the Canning and Southern rivers, which also led to the creation of Homestead Park.
He also initiated the Neighbour of the Year award and started the Thornlie Community Noticeboard Facebook page, which is now a well-used community resource.
Mr Hort said he only had positive memories of serving on council and thanked councillors for their contribution to his personal and professional development.
He noted some items that he would have loved to have seen come to fruition during his time on Council such as Hester Park, Local Planning Scheme 24 and the Rivers Regional Council Subsidiary.
Aside from those items, he said he believed council had achieved an enormous amount and that the future was very bright for the City of Gosnells.
