The 1991 election was a close election with Soorley just edging out the then Lord Mayor of Brisbane Sally Anne Atkinson through the preferences of Drew Hutton, the Greens candidate. Soorley was not expected to wrest the Lord Mayoralty from the very popular first female mayor of Brisbane. The transition period between Atkinson's administration and the incoming Soorley administration was difficult, with the outgoing Atkinson refusing to believe she had lost the election for many weeks afterwards. Soorley was a virtual "unknown" at that first election, but was one of the few Australian politicians to increase his popular vote in each of the next three elections, standing as Lord Mayor for 13 years. Soorley defeated the following Liberal candidates: 1991 Sally Anne Atkinson; 1994 Bob Ward; 1997 Bob Mills; and 2000 Gail Austen.

Soorley also instituted a number of institutional changes including a 24/7 Call Centre; "business style" accounting for budgets and annual reporting, enterprise bargaining, significant changes to leave and other entitlements, increased employment opportunities through increased apprenticeships, traineeships and community jobs programs, including a nationally awarded program for "at risk youth" who were recovering from drug addiction, as well as a shift from Brisbane Council being only concerned with "rates, roads, rubbish" to taking on issues such as drug use, homelessness, domestic violence and social justice. Before leaving office Soorley started the major infrastructure projects, such as the Eleanor Schonell Bridge from Dutton Park to St Lucia and North-South Bypass Tunnel.
