Certificate of Competency - Deck - Northern Territory


A Deck Certificate of Competency is required in order to operate as master or mate of a domestic commercial vessel. There are various prerequisites, courses and sea time requirements to be satisfied depending on vessel size and area of its operation.

Vessels operated commercially must be under survey unless exempted under the Northern Territory Marine Act. Depending on the size of the vessel and its propulsion machinery, a certified marine engineer may be required.

From 1 July 2018 this certificate will be administered by AMSA. Further information can be found at http://www.amsa.gov.au/vessels/national-system/seafarers/index.asp
