2019 Australian World Swimming Trials

The 2019 Australian World Swimming Trials are current being held from 9 to 14 June 2019 at the Brisbane Aquatic Centre in Brisbane, Queensland. The event is the selection trails for the 2019 World Aquatics Championships in Gwangju, South Korea.

Following Australia's performance at the 2016 Rio Olympics where 29 medals were won and finishing 10th on the medal tally, Swimming Australia announced in the February 2017 that the timing of the selection trails would be modified. Historically, the trails were held in April several months before the Olympics were held. This will be now changed to follow the American model where the trails are held six weeks before.

A Para Grand Prix will be held in conjunction with the trials on the 13 to 14 June 2019.

The legends relay was a mixed 4 × 50 m freestyle event swam on the fourth night of the meet. The team were:
 * Team Frame - Trevor Green, Marcelo Figueredo, Aaron Boersma and Linley Frame
 * Team Fraser - David Barrett, Brendan Dyer, Therese Crollick, Sandra Wylie
 * Team Rickard - Jane Sadler, Michael Lee, Jennifer Campbell, Brenton Rickard
 * Team Gallen - Jason Burgess, Jodie Greensill, Gillian O'Mara, Michelle Gallen
 * Team Flouch - Jamie Coates, Casey Flouch, Todd Robinson, Kylie Fletcher
 * Team Schipper - Martin Banks, Janette Jeffrey, Gerry Tucker, Jessicah Schipper

The event was won by Team Flouch in a time of 1:57.99, followed by Team Gallen (2:02.86) and Team FFrost where Nick Ffrost swam the backstroke and freestyle legs (2:17.02).
