The newspaper was founded as The Mount Barker Courier and Onkaparinga and Gumeracha Advertiser on 1 October 1880, price 3d. for 4 pages. Charles M. R. Dumas was sole proprietor, and its offices were on Gawler Street, Mount Barker. Publication continued every Friday morning. In 1893 tentative moves were made to introduce an alternative titleMount Barker Courier and Southern Advertiser, but somehow the "less cumbrous title" never made it to the front page. The newspaper later absorbed another publication, printed by Lancelot Ramsay Thomson, the Mannum Mercury and Farmer's Journal. Dumas, who was for four years Member for Mount Barker, died on 19 February 1935, and his family kept it running until May 1938, when it was taken over by T. H. Monger, previously owner of the Tasmanian King Island News. In 1909 Dumas opened a printery in Murray Bridge, and started a newspaper there, the River Murray Advocate, but by the start of 1911 the Advocate existed only as a single page supplement in the Courier. Monger's period of eight years, ending in March 1946, was short but eventful, encompassing World War II. The next owners were E. L. Perry and H. Edmondson. From 1952 the proprietors were F. T. Marston and E. L. Perry, and publisher was Norman E. K. Marston. In 1954, the last year which can be examined on-line using Trove, the newspaper's title was virtually unchanged, it had 10 pages, was published on Wednesdays and cover price was 4d. In 1960, the paper was abbreviated to The Mount Barker Courier, and to simply The Courier by 1983.
Today
, the paper has never missed a print run and is still in the hands of the same family, the Marstons. Its circulation is around 7,500. Norm Marston, son of the proprietor since 1952 and now over 91 years old, is very likely Australia's oldest active regional newspaper owner and editor. Four generations of the family have worked at the press.
