Southern Mallee District Council has a new mayor leading the charge, while Mid Murray Council has elected its new deputy mayor.
Councillor Jeff Nickolls is replacing Andrew Grieger as Southern Mallee's new mayor, and Paul Ireland will be supporting him as deputy mayor in his second one-year term in the role.
Cr Nickolls - who began his formal duties as soon as he was elected - was honoured to represent his community at that level, at "such an exciting time" for the district.
"We know there has been significant hardship in recent years with drought and now COVID-19 - however, we believe that we're moving into a new era in 2021, and I'm looking forward to working with our community to ensure our district continues to grow and prosper," he said.
"There is a lot to look forward to for our residents and businesses as this work comes to fruition. Together, we will put our district and the towns of Lameroo and Pinnaroo on the map and create new facilities for our community to be proud of and to enjoy."
The council thanked Cr Grieger for his service as mayor over recent years.
Mid Murray elected members unanimously appointed fellow councillor Simone Bailey as the new deputy mayor for a two-year term.
Cr Bailey, who represents the Shearer Ward, replaces outgoing deputy mayor Kevin Myers.
She has strong financial management skills due to her work in business management and accounting.
Cr Bailey looked forward to stepping into the position and taking on the extra responsibility such a role brings.
"I have learnt so much already in my first term as an elected member, and I'm excited to take on this new opportunity to expand my local government experience and skills, and to give back to council and the Mid Murray community," she said.
Mayor Dave Burgess said he was keen to work with Cr Bailey and listen to and deliver on the wishes of the community together.
"As a first-term councillor, serving in this leadership position will offer Cr Bailey new opportunities to continue to develop her skills as a leader within our local community and on our council," he said.
"Her appointment will also continue to raise the profile of women in local government and the value of diversity in these roles."
He thanked Cr Myers, who "generously served" the region as deputy mayor and will continue to do so as a councillor.
