After being second fastest through the heats to the final behind Jacques van Wyk in the 100m backstroke, the final panned out to perfection for KZN’s Justus.
Earlier, Van Wyk posted a time of 55.97, two hundredths of a second outside the Commonwealth Games qualifying time of 55.95.
Three swimmers led through the halfway mark of the final as Van Wyk, Justus, and Leith Shankland’s feet hit the wall almost simultaneously.
In the second 50m Justus, more known as a 100m freestyler, turned on the afterburners to secure the victory in 55,57, almost half a second faster than the Games qualifying time, and more than a second ahead of Van Wyk who recorded 56.64.
Martin Binnedel, national champion in 200m backstroke, claimed third in 57.01, ahead of Shankland who took fourth in 57.56.
In the women’s 50m breaststroke final, the top three spots went to swimmers who have represented the country at various levels this past season.
Fifty-metre events in backstroke, breaststroke and freestyle do not form part of the Commonwealth program, but it was still a good indicator of the form of the swimmers for later in the week.
Tatjana Schoenmaker won the event in 31.44, ahead of Caylene Corbett who did 32.36, with Hanim Abrahams in third place with 32.56. The first KZN swimmer to the wall was Emily Visagie in 33.28.
