Western Star in chronological order

Western Star Trucks Australia (WSTA) was formed in 1983 and secured the distribution rights for the Western Star product in Australia from Western Star Trucks Inc, based in Kelowna, BC Canada. The first Australian Western Star was built from CKD packs, in March of 1983, at the Wacol Qld facility. WSTA sold 53 Western Stars in that first year.

Heritage models 4864 and 4964 were produced from 1983 to 1989, and were offered with customised packages: Cheyenne, Apache, Comanche, Chinook, Mohawk, Pawnee and Navajo.

In February 1990, the first "Cornerstone" Heritage unit was introduced. Cornerstone was a project to reduce the cost and weight of the vehicles. This project introduced three new models: 4864S, a short-bonnet, set-back front axle prime mover for B-Double applications; 4964SS, a sloping, aerodynamic-long-bonnet truck, with 1270mm set-back front axle and 48-degree wheel cut; and 4864FX, a short-sloping-bonnet truck with enhanced visibility and a 840mm set-back front axle. The pre-Cornerstone 4964 continued for heavy-duty operations.

By 1991, the Western Star Truck parent company was in financial strife and the assets were purchased by the owners of the Western Star Australian subsidiary, Terry Peabody and Bob Shand.

In 1998 the Constellation Series was introduced, with a complete new cab and sleeper package that offered increased interior space and enhanced comfort. First models the 4864FXC, 4964FXC and 4964EXC, extended-bonnet truck.

In 2005 Western Star introduced the 4864FXB model that complied with the recently introduced 26-metre B-Double legislation.

The promotional edition of Model 4964 conventional truck was equipped with a Cummins Model NTC 444 engine, which was used in a Western Star truck for the first time. The truck is named "Premium Blue" for its distinctive six-color paint job (multi-colored laser beams on a blue field) and the color of the NTC 444 engine. Each of the Premium Blues was equipped with a 66-inch sleeper. They also featured a Rockwell FF941 front axle, and an Eaton DS381 rear axle as the standard spec.
