The changes were mainly as needed based for the general duties policing, with the addition of capsicum sprays, handgun, baton, etc. In 1981, female police officers were approved trousers as part of their uniform and they were issued 54 pantyhose a year. In 2001, the baseball cap was introduced along with akubra and a woollen jumper. One major change happened in 2008 with the introduction of the Integrated Operational Equipment Vest. In November 1986, Victoria Police announced the transition of the motto from "Tenez le droit" to "Uphold the right". This change would start taking place in December 1986.

The dark blue uniform was modelled after the Oxfordshire and Northumberland police attires. Ranks and Insignia Victoria Police has a quasi-military rank structure.
