The suburb takes its name from the town, which in turn was named after explorer
John Mackay, who led an 1860 expedition into the
Pioneer Valley. The original Mackay station opened in 1885 in Tennyson Street. In 1924, it was relocated to Boddington Street (). In the 1990s, the rail bridge over the
Pioneer River needed to be replaced, which presented an opportunity for re-alignment of the railway line to bypass the
Mackay CBD. In 1994, the new alignment opened with the new
Mackay railway station in the outer suburb of
Paget. St Patrick's College opened on 22 September 1929.Although
Maltese immigrants came to the Mackay area as early as 1883, it was not until in 1944 when Australia's immigration policy was changed to recognise Maltese people as "white British subjects" (and hence acceptable as immigrants under the
White Australia policy) that significant numbers of Maltese immigrated to Australia. Many of the Maltese immigrants to Queensland came to Mackay to work in the
sugarcane fields and later purchased sugarcane plantations of their own. In 2021, the
Mackay Regional Council gave approval for the Maltese community to erect bronze statues of 3 Maltese men sitting on the corner of Victoria and Wood Streets (a popular meeting place for the Maltese community). The statues will be based on a 1994 photo, which is currently in a plaque at the site. The statues are expected to be completed by April 2024. Mackay Opportunity School opened in 1960. On 29 August 1981, it was renamed Mackay Special School. It closed on 7 May 1997. Kutta Mulla Gorinna Special Assistance School opened in 2018. == Demographics ==
