Bourke returned to local politics in 1997, when he was elected Mayor of Toowoomba, having received a high-profile late endorsement from Berghofer. He pursued a policy of fiscal restraint as mayor, and touted among his successes as mayor the completion of an aquatic centre, water treatment plant, and securing a deal to sell sewerage effluent to the
Millmerran Power Station. He had an acrimonious relationship with the local media, and had received criticism for a perception of an 'abrasive' attitude towards ratepayers and council staff. He was reportedly the subject of a
Criminal Justice Commission inquiry into complaints of verbal harassment of council staff in 1999, but maintained there had never been a complaint lodged against him. He also had a highly publicised falling out with the city's chief executive officer, who subsequently resigned after an extended period on stress leave. He ran for re-election in 2001, but was defeated by alderman
Di Thorley. He sold his pharmacy business in 2002, and thereafter worked as a locum pharmacist in the Toowoomba area. He later contested the 2008 council elections for the new
Toowoomba Regional Council, but was unsuccessful. ==References==
