Emma McKeon may have been upstaged by Australian teammates the Campbell sisters in the 100-metre freestyle final, but the 20-year-old will leave Glasgow as queen of the pool.

Stepping out of the shadow of her brother David, Emma made her mark early in the campaign with gold in the 200m freestyle and her role in the 4x100m freestyle relay world record.

On Tuesday night she competed in her final event, the 4x100m medley relay, after collecting bronze in the 100m freestyle, behind Cate and Bronte Campbell.

The Olympics in Rio De Janeiro were already firmly in her sights, but expectations have only risen after her golden Glasgow heroics.

"She's really stepped up this season," Australian coach Jacco Verhaeren said.

"What I've seen from her this meet, she's really developed into a very stable swimmer who you can count [on] and, in all of her performances this year, I haven't seen a race that was poor or average.

"What I think is important is that she shows she is able to win close races. She still has quite a while to go to become apparently what she dreams of [but] she's one of our greatest talents in the team."

Meanwhile, Cate Campbell is waiting for the moment when younger sister Bronte finally trumps her in a competitive 100m freestyle race, having again managed to just hold on to win the Commonwealth Games gold.

Bronte has been setting a series of personal best times in Glasgow, also winning the bronze in the 50m freestyle and helping in the 4x100m freestyle relay team's gold.

Cate said she was immensely proud of the strides Bronte had made during the Commonwealth Games.

"She's come into her own," Cate said.

"She's a world record holder in her own right, and she's now been on an international podium in her own right twice, in world-class times.

"She's always said she never settles and this just proves it and I'm so grateful to have her by my side - both in the pool because she brings out the best in me there, and outside the pool because she's an incredible companion to work with".

In the 100m freestyle, Cate turned at halfway 0.45 seconds under Britta Steffen's supersuit world record pace but faded in the final stages to finish in 52.68 seconds.

Bronte touched in 52.86, which was the first time she had beaten the benchmark time of 53 seconds.

McKeon completed Australia's second clean sweep of the night, winning bronze with a time of 53.61.

Bronte said although she had played second fiddle to Cate for most of her career, she was not driven to knock her off her perch.

"I don't want to strike Cate off any list," she said.

"It's great to race Cate and I don't make it my goal to beat her. I make it my goal have a win for myself and coming second to Cate, that's a win for me, doing a good time, that's a win for me - it might sound stupid but I don't enter a race to win, I enter a race because I love racing.

"I love standing up behind the blocks and I love that moment just before you dive in and it goes quiet and you take a deep breath and you just dive and then you try and win - but that moment just before I go, that's why I race.

"Not to try and beat Cate, not try and beat Emma, it's just that little moment before I go."
