The 28-year-old, who has competed at the last three Paralympic Games, claimed victory in a time of 32.22sec at the Championships at the SA Aquatic & Leisure Centre in Adelaide.

His time proved faster than the previous best effort at the distance by Poland’s Damian Pietrasik back in 2005.

The event, though, will not appear on the Rio 2016 swimming programme,.

McClure will take confidence from his display, however. 

In the S14 women’s event Taylor Corry earned a gold medal in a time of 32.17, with her compatriots Nicole Miro and Madeleine McTernan clocking times of 34.08 and 34.07 respectively in the mixed classification event.

Miro was, therefore, awarded the silver medal having earned 803 points, with McTernan a further two behind.

Paralympian Ellie Cole broke the second world record at the event, the 24-year-old finishing the women's S9 50m freestyle event in a time of 28.75.

The three-time world champion’s time lowered the previous mark, which had stood for eight-years.

She will hope to continue her form as she chases further Paralympic success, having earned four gold medals at London 2012.

Tiffany Thomas Kane claimed the Australian title in the women’s S6 200m individual medley, the 14-year-old finishing the distance in 3min 08.98sec.

It was announced earlier this month that Jacqueline Freney, winner of eight Paralympic gold medals at London 2012, will not compete at Rio 2016.

The 23-year-old won more gold medals than any other athlete at London 2012 but will be absent in Brazil after a "medical mystery problem" forced her to miss the Championships.

The Australian Swimming Championships act as the trials for both the Olympics and Paralympics.
