South West Coach Lines was founded in 1977 by David and Lenita Adams. In January 1986 it commenced operating the
Bunbury City Transit service replacing
Love's Bus Service. The fleet consisted of eight
Howard Porter bodied
Mercedes-Benz OH1316 buses painted in a livery of white with sky and royal blue bands. In 1988 it commenced operating a three times weekly service from
Mandurah to
Pinjarra under contract to the
Government of Western Australia. In November 2007 the business was purchased by
Veolia Transport and in July 2013 became part of
Transdev. In December 2009, South West Coach Lines commenced operating three services in
Busselton under the TransBusselton brand under contract with the
Public Transport Authority. Upon being re-tendered, the routes passed to
Swan Transit from 1 January 2015. In 2011 the Bunbury services were rebranded as
TransBunbury with the Public Transport Authority acquiring the fleet and depot from Veolia and introducing its silver and green livery. In 2015 South West Coach lines was sold to the
Australian Transit Group. ==Fleet==
