After completing a degree in physiotherapy Bronwyn returned to athletics in 2000, and later that year represented Australia in the long jump at the 2000 Olympic Games in Sydney, narrowly missing a place in the final. Her performance was hampered by a large tumor which had been discovered in her take off foot, and after the games Bronwyn underwent surgery to have it removed. In 2001 her performances continued to improve, and she broke the Australian long jump record, previously held by Nicole Boegman. In 2002 Bronwyn improved her Australian record with a jump of 7.00m, which remains her personal best. She was again restricted by injury at the 2002 Commonwealth Games in Manchester, finishing sixth in the long jump despite going in as the favourite. At the 2003 World Championships in Paris, Bronwyn finished seventh in the final, despite further injury concerns.
