Following the opening of Chadstone Shopping Centre in 1960 services from Burwood and South Oakleigh were added.

[3] In the 1950s and 1960s, a number of operations were purchased:[3][5] In 1957, a new depot was opened on the corner of Centre and Warrigal Roads, Oakleigh.

[8] In February 2000, Ventura purchased Mount Dandenong Passenger Service from the Frazer family.

[10][11][12] In December 2009, Ventura purchased US Bus Lines from the Pulitano Group, operating route services in the outer east region.

[14][15][16] As part of the financing of the deal a 15% stake in Ventura was sold to the Intermediate Capital Group.

Many non-Leyland buses joined the fleet including Bedfords, Elwoods, Mercedes-Benzs and Volvo B10Ms.

When Ventura sought new buses in 1992 Leyland had ceased production, so two Scania L113s and a Volvo B10M with Volgren bodies were purchased for evaluation.

[1] In 2017, the company began to integrate technology to track buses in real time across its route services.

New deliveries are receiving the Public Transport Victoria white and orange livery with existing buses progressively repainted.
