Hobart's ratepayers deserve an apology from outgoing Lord Mayor Sue Hickey after a massive travel expense blowout, according to a fellow alderman.
Marty Zucco claims Ms Hickey has spent more ratepayers money on travel than the Lord Mayor of Melbourne or Tasmania's Permier.
He says Ms Hickey was elected on a platform to rein in spending.
"Pre 2015 there were only nine overseas trips over a three year period," he said.
"Since 2015. over a three year period, there's been 27.
"I don't believe that there is a need for that much overseas travel by any alderman on any committee."
