The Queensland State Championships wrapped up Thursday in Brisbane, Australia, with the country's best swimmers warming up for a hotly contested domestic summer season — peaking with the Commonwealth Games in April. 

Here are the top performances from the meet. 

Ariarne Titmus

The 17-year-old was the breakout star of the meet, capping a huge 2017 in which she finished fourth in the 400m freestyle at the World Championships in Budapest and claimed bronze in the 4x200m free relay. 

She defeated Olympic medalist Emma McKeon with a 1:56.34 on night one, and 24 hours later Titmus broke the Australian record with her 4:02.86 in the 400m free. Both were personal best times. She finished the week with a 8:25.22 in the 800m free. 

Cate Campbell

The elder Campbell sibling posted her fastest times of the year at this meet with a 24.13 in the 50m free and 52.69 in the 100m free. Fun fact: her 100m time was faster than the winning time from Rio.

Elijah Winnington

Another Aussie teenager threatens to break out in 2018, with world junior medalist Winnington defeating an experienced field to take the 200m freestyle in 1:47.96. The 17-year-old also swam a personal best 3:50.20 in the 400m free to push Mack Horton all the way. 

Mitch Larkin

The dual world champion Larkin has returned to his roots at St. Peters Western after an off year in 2017. He bounced back to form in Brisbane, swimming times of 54.03 and 1:57.41 in the 100m and 200m backstroke events and 1:58.89 (personal best) and 4:20.45 in the 200m and 400m IMs.

Men’s 100m Free

All eyes were on James Magnussen as he swam a 48.90 for the top seed after the heats. He had some added pressure on him as well after Sydney Olympics relay gold medalist Ashley Callus sparked a war of words in the Aussie media. Magnussen got the win in the final, albeit with a 49.23, but in a hot field where he defeated Jack Cartwright (49.33), Kyle Chalmers (49.60), James Roberts (49.85), and a lackluster Cameron McEvoy, who finished sixth in 50.10. 

The Australian team will again be competing at the Victoria State Championships (Jan. 12-14) and the New South Wales State Championships (Jan. 19-21), before the National Championships start Feb. 28.
