Samuel Peter Mackay was a pastoralist and businessman in Western Australia. His parents were pioneers from the Isle of Skye who settled in Victoria in 1852. Mackay was born in 1864 and was educated at Mount GambierGrammar School but left at age 13. He worked as a drover and a surveyor before deciding to move to Western Australia along with his father, Donald MacKay, and uncles, Roderick Mackay and Donald McDonald. Together the men worked in the pearling industry in the NorthWest region. De Grey Station was owned by Mackay in 1875 and was briefly managed by George Julius Brockman for three months of the same year while Mackay travelled to Melbourne. Realising the pastoral prospects of the country, the men bought the Mundabullangana Station in about 1880. The Mackays were involved in the racing industry and in breeding horses on the station. Following the death of his father in 1903 Mackay bought out his uncles and became the sole owner of the property. MacKay bought and sold many stations throughout the northwest part of Western Australia; J. G. Meares sold his share of Sherlock Station to Mackay in 1910. Later the same year, Mackay acquired the Springs station, which he sold in 1910 to S.L. Burges. In 1911, MacKay unsuccessfully bid £25,000 for the Croydon Station, which adjoins Pyramid Station. MacKay acquired Croydon at a later date and sold the property stocked with 12,000 sheep in 1921. At one time Mackay had also acquired Balmoral Station from James Munro; he later sold it to B. H. Sharpe and Company. Mackay left Western Australia in 1905 and returned to Victoria while retaining his pastoral interests. He bought Melville Park where he lived until 1912, then moved to St Kilda and eventually to Rock House Estate near Kyneton, where he hoped to establish a horse stud. In early 1922, while in Perth, MacKay had to have his leg amputated. He eventually returned to Melbourne but died on 11 May 1923 while in hospital. He was buried at Brighton Cemeterythree days later with several prominent members of the racing community acting as pall-bearers. In the 1920s Mackay's daughter Elsie Mackay became a notable actress in Britain, the United States and Australia.
