A pair of Kangaroo Bus Lines work horses back in 2009 and still going in 2018 were 39 and 40 (KBL39/40), both Mercedes OH1418 models with 1993 Newnham body (39) or 1994 Custom body (40). Both came from Skybus where they were 54/55 (1981/1982AO).
Dee Decker in Melbourne acquired this 1984 Newnham bodied Volvo B10M with a checkered past from Victorian Touring Coaches where it was 22 (1622AC), before that it was with Five Star Coaches of Greensborough and Skybus, but they bought it from Chris's Coaches in Victoria when it had rego CFW990. It is seen on Victoria Parade near St Vincent's Hospital in December 2015.
