Mostert hails from Bloemfontein in South Africa and came to Suncorp Super Netball via Team Bath in England.

Karla represented South Africa at Netball World Cup 2015 (No. 1 ranked GD for intercepts at the tournament), the 2014 Commonwealth Games, 2011 Netball World Cup and more recently in the Netball Quad Series against Australia, England and New Zealand. The Lightning defender was one of the first athletes picked to represent South Africa at the 2018 Commonwealth Games on the Gold Coast. In 2016 she was playing in England’s Super League for Team Bath.

Robust yet unassuming, the Proteas’ powerhouse has an incredible netball I.Q. and excelled in Lightning colours under the watchful eye of Coaches Noeline Taurua and Kylee Byrne.

Her dominant display in the 2017 Suncorp Super Netball Grand Final earned the quiet achiever MVP medal after helping keep GIANTS Netball to its equal lowest total of the season (48).

Also capable of slotting into the Wing Defence bib, Mostert was a vital cog in Lightning’s defensive unit during the 2017 league. Her eye-catching performances  were rewarded with the Proteas’ Vice Captaincy.
