In November 2012, Transit Systems was awarded a contract by Transport for NSW to operate region 3 bus services in Western Sydney, taking over services operated by Busabout, Hopkinsons, Metro-link and Westbus. Transit Systems also took over route T80 on the Liverpool-Parramatta T-way from Western Sydney Buses. Operations commenced on 13 October 2013.
On 1 July 2018, Transit Systems took over the operation of region 6 from State Transit on an eight-year contract operating services in the Canterbury-Bankstown, Eastern Suburbs, Inner West, North Shore and St George regions.
In region 3, Transit Systems operates a combination of buses inherited from its predecessors, 65 new built buses and some second hand purchases including Volgren bodied Mercedes-Benz OC 500 LEs from Brisbane Transport and some older high-floors purchased from the Dineen Group and Hopkinsons. In mid 2017, Transit Systems purchased six Bustech CDi double deckers for use on route T80.
In region 6, Transit Systems inherited all of the Inner West State Transit fleet. This consists of a wide variety of different buses, both new and old, and with many different chassis and body types. Since they have acquired the contract, they have also purchased many new buses for this region. Most of these buses are similar to ones inherited from State Transit, but they have also bought buses from Gemilang Coachworks, which State Transit does not buy from. Transit Systems were also selected to trial 5 electric buses in the Inner West region.
As of January 2021, the total fleet consists of 857 buses. 235 buses operate in region 3 & 622 buses operate in region 6.
