St Lucia is a suburb within the City of Brisbane, Queensland, Australia 6 kilometres (3.7 mi) southwest of the Brisbane CBD. The suburb sits on a peninsula, bounded on the north, east and south by a bend in the Brisbane river. The eastern third of the suburb is occupied by the main campus of The University of Queensland. The flat area on the northern side is primarily medium to high density residential including numerous high-rise apartments on the river-front. The more hilly area in the centre and south is mainly low-density residential. The south-west is occupied by the Saint Lucia golf links.
St Lucia is mainly a residential suburb and is generally regarded as one of the most affluent suburbs in Brisbane. For many years it was the third most expensive suburb behind Hamilton and Ascot and is still one of the top five most expensive suburbs in Brisbane today.
