Metro-link Bus Lines was established in November 1954 when the Oliveri family, trading as Oliveri Transport Service purchased route 41
Liverpool station to
Green Valley. In November 1988, it was merged with
Ingleburn Bus Service, which the Oliveri family also owned, and in July 1989 both were renamed Metro-link Bus Lines. In September 1993, the business were again separated. From 2005, Metro-link's services were part of
Sydney Bus Region 3. In October 2013,
Transit Systems NSW commenced operating Region 3 including the services formerly operated by Metro-link. Transit Systems leased Metro-link's Green Valley depot, which opened in December 2010. After operating as a charter operator out of another depot in
Ingleburn, Metro-link later returned to the Green Valley depot. From the 1970s until the early 1990s, a coach charter operation was operated under the Relaxaway Tours banner. ==Fleet==
