Saturday, 28 October 2017: Emily Seebohm stands alone in Australian short-course swimming history topping Matt Welsh's tally of 24 gold medals to win 25 and she's not done yet.

Emily Seebohm has eclipsed Matt Welsh as Australia's most successful Australian short-course swimmer by winning a 25th national title at the 2017 championships in Adelaide.

The 25-year-old triple Olympian and five-time world champion, added her third victory of the event in the 100m backstroke in Friday night's finals session.

Seebohm's win in 56.80sec followed her previous wins in the 200m backstroke and the 100m individual medley.

It took Seebohm past Sydney 2000 Olympic backstroke medallist Welsh, who won 24 titles between 1997 and 2007.

And she's not done yet.

Seebohm gets the chance to extend her tally with the 200m individual medley and the 50m backstroke still to come on the program.

In another record breaking night at the SA Aquatic Centre, Thursday's world record setter in the 100m freestyle, Cate Campbell, added the Commonwealth record in a sizzling 50m freestyle showing.

Campbell clocked the third fastest time in history - just 0.26 outside Dutch swimmer Ranomi Kromowidjojo's world mark of 22.93 set on August 7 this year.

Grabbing a sprint trifecta for coach Simon Cusack, 18-year-old rising star Shayna Jack squeezed in between the Campbell girls in a personal best time and sixth fastest time by an Australian in 24.01 with Bronte Campbell a fingernail behind in third in 24.03.

Seebohm's first titles came in 2009 with the 50m and 100m backstroke and 100 and 200 individual medley doubles.

It was the start of what has been a stellar and versatile short-course career - winning medals across an unprecedented nine events.

And there is no sign of her stopping any time soon with plans to contest the Asian Cluster of the FINA World Cups before the end of the year.

She will then set her sights on next April's Gold Coast Commonwealth Games and she plans to train up until 2020 and try and emulate the great Leisel Jones and make her fourth Olympic team.

"I didn't realise it was so many, it is definitely very exciting and I've worked really hard and I didn't really come into this (meet) with a goal of getting more national short-course titles," said Seebohm.

"I came here for some hard training and you saw that (Thursday night) when I did over one kilometre in racing which is unusual for me, but it definitely helps toughen you up.

"It's good to come here and do some stuff you don't normally do and I guess to experience another level of fatigue and tiredness; it is definitely hurting me today but it's all part of the game."
