Olympic silver medallist Mitch Larkin has his Commonwealth Games campaign on track with two gold medals within 40 minutes at the Queensland swimming championships.
The 24-year-old opened Tuesday night in personal best form, winning the men's 200m individual medley in his best time of 1:58.89 - a firm indication he would add the medley to his program for February's Australian Championships and Games trials.
Larkin was back in the pool 40 minutes later at the Sleeman Aquatic Centre for his specialist 200m backstroke final, winning in 1:57.41 - adding to his victories earlier in the week in the 100m backstroke and 400m individual medley.
"I only swam down about 200 metres so my legs were a bit cooked," said Larkin.
"It shows I'm in pretty good shape; physically, I feel pretty good now. A PB in the medley so it was a good night.
"I'm pretty happy with where things are now with a couple of months until trials and I think this meet will really give me that confidence in the work I am doing with coach Dean Boxall and give me that spark for the last couple of months into trials.
"I knew I was physically getting into good shape and starting to swim some good times. But it's until you get back in the pool and racing and your races unfold the way you've been training, it gives you that much more confidence and that inner belief that I sort of lost a bit in the last 12 months and it's really coming back quite quickly now and I'm really happy with that."
Larkin's teammate Ariarne Titmus wrapped up a rare treble when she added the 800m freestyle to her impressive wins in the 200m on Monday night and 400 metres in a new Australian record time.
Titmus led from the outset moving through the 200m in 2:01.10 and the 400m in 4:08.08 before feeling the pinch of her heavy training and racing schedule to win in 8:25.22 - just two seconds outside her best time.
Other winners on Tuesday night were Sian Whittaker in the 200m backstroke (2:10.35) and Emma McKeon in the 200m butterfly (2:09.33).
David Morgan took the men's 200m butterfly in 1:58.58; and American Jordan Wilimovsky overtook Mack Horton to win the 1500m freestyle in 15:08.98 to Horton's 15:15.49.
