In 1966 Frank Bono and George Sita purchased route 406 Footscray - East Keilor. In 1968 Sita sold his share to Bono. In January 1972 Sita purchased Graingers Bus Lines with 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.
Sita commenced coach operations in 1982 initially with second hand Denning vehicles, before building up a large Austral Tourmaster fleet from 1984. In 1995 Sita purchased the Coachtrans coach operation on the Gold Coast and commenced operations in Sydney. The latter operation has since ceased.
As of March 2015[update], the fleet consisted of 174 buses and coaches. Sita's bus livery is white at the top and fawn at the bottom with an orange stripe. A special orange, white and black livery is seen on buses dedicated to the 401 shuttle from North Melbourne station to Melbourne University via the Royal Melbourne Hospital. Coaches were painted in a red, yellow and white livery, but are now painted white.
