In the 1960s Bayside Buslines was formed when Black & White Safety Bus Line and Blue & Silver Buses merged.^[2] In 1985 Bayside Buslines was sold to current Transit Systems owners Lance Francis, Graham Leishman and Neil Smith who owned Peninsula Bus Lines on the New South Wales Central Coast. In 1989 Bayside handed in its licences to operate in Lota, Manly and Wynnum, the services having become unprofitable following the reopening of the Cleveland railway line retaining its Redland City services.^[3]

In February 1991 Bayside along with Sunliner Express was placed in administration.^[4] The business continued to be operated by its administrator until sold in July 1992 to Geoff Todd.^[5]

In September 2004 National Express sold the business to Connex and renamed Connex Brisbane.^[9][10][11] In January 2006 it was rebranded as Veolia Transport.
