A fee or payment made for publishing something in a gazette; the charge for official publication or announcement.
From 'gazetteer' (a person who publishes or edits a gazette) plus the suffix '-age' (forming abstract nouns from other nouns, indicating a process, collection, or payment), similar to 'brokerage' or 'steerage.'
The '-age' suffix is wonderfully productive in English for creating nouns about fees, processes, and collections—you can add it to almost any profession and suddenly you have the word for its charges or practices.
