Brisbane City Council's overseas travel expenses soared to $185,000 in the past financial year, more than double the previous period's figure and a six-fold increase on 2015-16.

There were 30 overseas trips made by staff and counsellors in 2017-18, which was double the number of trips from the previous year.

Opposition leader Peter Cumming said he was astounded the overseas travel bills had gone sky-high under lord mayor Graham Quirk, claiming they should have gone down. He also made a comment that “Council officers should spend more time behind their computers and less time on planes.”
