The Illawarra Mercury is published from Monday to Friday with a weekend edition published on Saturday, in Wollongong, the third largest city in the State of New South Wales, Australia. It has been published since 1855, making it one of Australia's oldest newspapers and the second oldest regional newspaper in New South Wales. It has been published daily since December 1949, and has had no competition since the 1960s.
The Mercury once was jocularly known as The Mockery among residents of the Illawarra region due to its perceived shallowness of coverage and lack of accuracy. As a result it became a running gag on the ABC's Media Watch in the period when Stuart Littlemore hosted the programme, and The Mercury was edited by Peter Cullen. The Mercury is published in the standard Australian tabloid format, with each page having an approximate size of A3.
The Illawarra Mercury was established by Thomas Garrett and W. F. Cahill in 1855.  The first issue was printed as 8 large folio pages and was circulated on the 8th October 1855. Initially the newspaper was published once a week then increased to twice weekly in 1929. During the 1930s the depression had a significant effect on the region and forced the newspaper to revert to a weekly publication. It wasn’t until 1950 that the newspaper increased its publication to a daily paper; this led to the newspaper changing its name to the Illawarra Daily Mercury, which lasted until 1954. In 1979 and after having dropped the ‘daily’from its title the Illawarra Mercury officially became a metropolitan daily newspaper.
One of the significant events of the newspaper includes the amalgamation with the Bulli Times and Port Kembla Pilot in February 1949. The paper also later merged with the South Coast Times in 1968.
In 1981 the Illawarra Mercury acquired a new offset press that allowed the newspaper to be brought to life in full colour. As technology emerged an order was placed in 1988 for a new electronic colour scanner which would enhance the newspapers production and appearance. It was the first newspaper in Australia to use the state-of-the-art Itek 210S scanner.
In 2012 Fairfax relocated the editorial production of Illawarra Mercury to New Zealand.

Despite being marketed towards residents of the Illawarra and surrounding regions, it can be purchased throughout the Sydney metropolitan region where it is popular due to the high quality of its horse-racing and sport coverage.
In 2005 The Mercury was named Newspaper of the year 20,000-50,000 circ. by the Pacific Area Newspaper Publisher's association PANPA.
In 2004 the Illawarra Mercury won the Walkley Award for Investigative Journalism and the Pacific Area Newspapers Publishers’ Association Marketing prize.
Its editorial cartoonist, Vince O'Farrell, has won international awards for his work - his cartoon immediately after the September 11, 2001 attacks depicting tears rolling down the Statue of Liberty's cheeks is one example. O'Farrell is a six-time winner of the Rotary cartoons award.
The Illawarra Mercury in 1972 won two of the State’s leading newspaper awards – a W. A. Richard award for technical excellence in newspaper production and a ‘certificate of merit in journalism’.
The newspaper is available on microfilm at Wollongong City Library and the State Library of New South Wales. It has been digitised by the National Library of Australia under its Newspaper Digitisation Program.
