Star Kingdom was purchased by Alf Ellison, Reg Moses and Stanley Wootton at a cost of £4,000 and sent to
Australia in 1951. Upon arrival it was obvious that he had not travelled well, and he stood only 15 hands and inch high, leaving his purchasers with serious doubts about the wisdom of their choice. As there was already a Star King in Australia, he was re-registered as Star Kingdom and installed at
Baramul Stud in
New South Wales. His influence was not immediately felt, but eventually he became Australia's leading sire for the first time in the 1958–59 season when his fifth crop began racing although he was the leading sire of two-year-olds in his first season and the first sire whose earners were to reach the equivalent of $2 million. Star Kingdom was the leading sire five times, leading sire of two-year-olds seven times as well as leading the broodmare sires' list thrice. A headstone at Baramul Stud commemorates him and his son, Todman. In 1978, more than 11 years after Star Kingdom's death, he had at least 42 sons standing at studs in Australia and New Zealand, including the very successful Kaoru Star. At the same time he also had over 100 grandsons standing at stud. ==Pedigree==
