NSWIS swimming siblings David and Emma McKeon didn’t just win berths onto the Commonwealth Games team in Brisbane – they secured a family legacy on the opening night of the 2014 Australian Swimming Championships.

The pair, who won the 400 and 200m freestyle respectively – will now head to their first Commonwealth Games, following in the wake of mum (the former Susie Woodhouse), dad (Ron McKeon) and uncle (Rob Woodhouse).

Emma, who won the 200m free in the Australian record time of 1:55.68, was adamant their family pedigree had provided the inspiration and not the pressure to perform.

"My mum, dad and my uncle all made the Commonwealth Games team in the same year. Now me and my brother have made it,” she said at the Chandler Aquatic Centre.

"There’s definitely no pressure at all. I just do it because I enjoy it.”

David’s time of 3:43.72 was the second fastest mark set this year and would have won him a silver medal at last year’s world championships in Barcelona.

In other events, 15-year-old Madison Elliott took out the women’s 50m freestyle Multi-Class final breaking the S8 world record in 31.13 seconds. 

Daniel Tranter finished second in the men’s 200m breastroke, four seconds behind 100m world champion Christian Sprenger, whilst Mitchell Kilduff and Andrew Pasterfield placed second and third in the Men’s 50m Freestyle Multi-Class.

Jayden Hadler was second faster qualifier in the semi-finals of the men’s 50m butterfly, swimming 23.95 for the one lap dash, with Emma McKeon fourth fastest in the semis of the women’s 100m butterfly.

Night two of the 2014 Australian Swimming Championships can be seen LIVE on ONE HD from 7.30pm AEDT.
