5277 Brisbane           Discovered 1988 Feb. 22 by R. H. McNaught at Siding Spring.
Brisbane, the name of the capital city of Queensland, itself honors Sir Thomas Makdougall Brisbane, an astronomer and the colonial governor who established Australia's first permanent observatory in 1822. The minor planet's discoverer was born 20 km from Brisbane's birthplace in Ayrshire, Scotland.
