In 1966, Frank Bono and George Sita purchased route 406 Footscray - East Keilor. In 1968, Sita sold his share to Frank Bono.[2] In January 1972, Sita purchased Grangers Bus Lines, which operated route 472 Moonee Ponds Junction - Williamstown Beach. Subsequently purchased were Murrays Coaches in 1975, Nidis in 1979, West Newport Bus Service in November 1980, Sunshine Bus Lines in April 1982 and Starline Coaches in 1985.[3][4][5]
Sita commenced coach operations in 1982, initially with second hand Denning vehicles, before building up a large Austral Tourmaster fleet after 1984.[4][6] In 1995, Sita purchased the Coachtrans coach operation on the Gold Coast and commenced operations in Sydney.[7] The latter operation has since ceased.
On 1 July 2018, Sita commenced a new ten-year performance-based contract to operate its bus services.[8] In April 2019, Sita was purchased by Transit Systems,[9] and was re-branded Transit Systems Victoria in November 2020.[10]
Fleet
As at December 2022, the Transit Systems fleet consisted of 166 buses and coaches.[1] Sita's bus livery was white at the top and fawn at the bottom with an orange stripe. A special orange, white and black livery was used on buses dedicated to the 401 shuttle from North Melbourne station to Melbourne University via the Royal Melbourne Hospital. Coaches wore a red, yellow and white livery, but are now painted white.
