Born in Rustenburg, Transvaal, Brits began her cricket career aged 11 when she entered the sport playing in boys' teams.
[6] At the age of 14, Brits made two appearances for South Africa Under-21s women against the touring England side in 1998, playing as wicket-keeper during two 50-over contests.
In the fourth ODI, she was promoted up the batting order to number five, though she only managed to score ten runs as South Africa failed to chase down an Indian total of 160.
During three 50-over warm-up matches, Brits claimed four wickets and scored 33 runs while opening the bowling and batting as part of the tail.
[13][14][15] During the first Test, Brits showed her ability with the bat, scoring 32 runs as part of a 59-run partnership with fellow tail-ender Sune van Zyl.
[18][19][20] She continued her string of ducks in the first-innings of the second Test, falling leg before wicket (lbw) facing her eighth delivery.
In the first match, Brits claimed three wickets as England were restricted to 151, a total South Africa passed with the last ball of the allocated 50 overs.
Despite her wickets, England set South Africa a total of 242 to chase, and Brits was moved up the batting order to open the innings alongside Terblanche.
[26][27] She enjoyed more success during the tournament itself, finishing as South Africa's leading run-scorer with 206 runs, 92 more than her closest compatriot, Shandre Fritz.
During South Africa's second round-robin match, against the West Indies women, Brits made both her highest score of the tournament, making 72, and her best bowling analysis, taking four wickets.
Despite Brits' relative success in the tournament, the win against the West Indies women was South Africa's only victory, and they finished the group stage in seventh place, meaning that they failed to qualify for the knockout phase.
[33] An injury to Fritz, who had been selected as South African captain for the home series against Pakistan in 2006–07, saw Brits named as her replacement eight days before the first ODI.
[49] Brits was not required to bat in the first match, a ten-wicket victory over Bermuda in which eight of the Bermudans failed to score a run, and the remaining three were all dismissed for just one apiece.
Coming in at number three after opener Daleen Terblanche had been dismissed for a duck after five balls of the match, Brits batted through the remainder of the innings and finished on 107 not out.
[55] Upon the completion of the competition, the national team flew over to Ireland to begin their tour of the United Kingdom which started with an ODI just four days later.
South Africa enjoyed a comfortable ten-wicket victory in the tour opener, with Brits bowling an expensive two overs, conceding 17 runs including eight wides.
Denise Reid, the convenor of selectors, stated that the change had been made in order for Brits to "concentrate entirely on her own performance" as "[South Africa] require her undivided attention at the role assigned to her".
[69] Her half-century against New Zealand in the second match is the highest score by a South African woman in a Twenty20 International, surpassing the record of 38 set only four days earlier by du Preez.
Brits top-scored for the South Africans in the first of four ODIs with 48, but an unbeaten century from West Indies opener Stafanie Taylor helped the tourists to chase down the total and win with 51 balls remaining.
