St Lawrence was the administrative centre of the Shire of Broadsound until 2008, when the shire was amalgamated with the Shire of Belyando and the Shire of Nebo to form the Isaac Region local government area. Moranbah is the administrative centre of the new region but the former Broadsound Shire offices at 36 Macartney Street are still used as the local offices of the Isaac Regional Council. The building was described in 2004 as "a disarmingly elegant building which seems quite out of place in this otherwise undistinguished town".
