The functions of the governor-general include appointing ministers, judges, and ambassadors; giving royal assent to legislation passed by parliament; issuing writs for election.

In general, the governor-general observes the conventions of the Westminster system and responsible government, maintaining political neutrality, and has to always act only on the advice of the prime minister.

The governor-general also has a ceremonial role: hosting events at the official residence—Government House in the capital, Nassau—and bestowing honours to individuals and groups who are contributing to The Bahamas and to their communities.

As the sovereign works and resides predominantly outside of Bahamian borders, the governor-general's primary task is to perform the monarch's constitutional duties on his or her behalf.

[5] The governor-general acts on the advice of the prime minister, to issue regulations, proclamations under existing laws, to appoint state judges, ambassadors and high commissioners to overseas countries, and other senior government officials.

[2] The governor-general is also responsible for issuing Royal Commissions of Inquiry, and other matters, as required by particular legislation; and authorises many other executive decisions by ministers such as approving treaties with foreign governments.

[7] The governor-general provides non-partisan leadership in the community, acting as patron of many charitable, service, sporting and cultural organisations, and attending functions throughout the country.
