The Geraldton Guardian was established at Geraldton, Western Australia on 1 October 1906 to serve the Victoria and Murchison Districts. It was launched on principles of liberal democracy, state rights, nationalism and British preference.
The Geraldton Guardian was established by the proprietors, Constantine and Gardner, at the "Guardian Buildings", Marine Terrace, Geraldton, Western Australia.  Edward Constantine, the senior partner of Constantine and Gardner was born in Cornwall, England but emigrated to South Australia with his parents at the age of three. 
Initially the Geraldton Guardian was published biweekly on Tuesday and Friday. It consisted of eight demy-folio pages printed on a demy Wharfedale machine.  Starting on the 15th of October 1907, publication changed to tri-weekly on Tuesday, Thursday and Saturday. It was now bring printed on a super double royal Wharfedale powered by a 5 horsepower engine.
On 1 January 1929 the Guardian amalgamated with the other Geraldton newspaper, the Geraldton Express (established in 1878), and was published as the Geraldton Guardian and Express, an evening daily.
On 1 January 1948 it changed its name back to the Geraldton Guardian.
