RICHLANDS councillor Milton Dick has vowed to hold the Brisbane City Council to account, following his unanimous appointment as Opposition Leader last week.
As support for Labor dwindles, Cr Dick said his electoral victory and new leadership role was a double vote of confidence.
"It's a huge responsibility, but my first commitment will always be to the people of Richlands who have endorsed me as their local councillor," he said.
"They put their trust in me with their support. I need to repay that debt through hard work and delivery every day for the next four years."
Cr Dick said his new position would give him greater opportunity to speak out and to advocate on behalf of local residents.
"It will enable me to fight harder for some local issues, particularly in the areas of cost of living.
"I want to make sure the council delivers low and fair rates, particulary with the upcoming budget, to deliver real practical relief for people who are doing it tough financially."
With labor holding only seven of Brisbane's 26 seats, Cr Dick described the next four years to be like "climbing Mt Everest without oxygen".
He said him and his fellow Labor councillors had a tough job ahead of them.
"To defy the political odds, is very humbling. I don't take it for granted.
"It's my job to keep them on their toes and make sure they deliver on their commitments and promises, particularly on the issues of cost of living.
"My door is always open. I am happy to sit down with the Lord Mayor any day of the week to look at any good ideas for the local community and the people of Brisbane.
"At the end of the day, people expect us to get on with job, work as hard as we can and deliver for their local communities.
"I want to see if we can put the politics aside, and deliver real positive outcomes because my community deserve nothing less."
In the upcoming budget, Cr Dick said improving public transport and delivering cost of living relief was his main priority as newly elected Opposition Leader.
The announcement followed the release of the final tally of votes for the local government election last Thursday, which showed a 67% majority support for Cr Dick.
