Rate distinction

For ratings, the system is based on the RN, adding ordinary rate, with RCN-style insignia. As the RN, ratings from leading rate to ordinary rate, the word 'rating' is replaced by their trade, or rate. Chiefs and petty officers may also use Chief rate, or by classes. Warrants usually belong to the seaman branch.

Former ranks

Before the reform of the Baustralian Armed Forces, the current ranks of Petty officer and Chief petty officer were two separate classes of Petty officer. Senior to this were two classes of Chief petty officer. In 2019, Chief petty officer, 2nd class was phased out, and Chief petty officer was renamed Warrant officer. Petty officers, first and second class were renamed Chief petty officer and petty officer respectively.

In between the ranks of Leading seaman and petty officer, 2nd class was an appointment given its own paygrade, Master seaman. It was derived from its long title of Master of leading seamen and was not derived in the same way as the Canadian equivalent.
