Following South Africa's expulsion from international cricket, South Africa women played their first match for 25 years in August 1997. Playing against Ireland, Terblanche and her ten teammates made their international debuts. After losing the toss, South Africa put on 175 runs, Terblanche hitting 28 from number six.[6] In reply, Ireland were bowled out for just 82, giving South Africa the victory on their return.[6] South Africa went on to win the three-match series 3–0, and went straight into a four-match series against England, which they lost 2–1.
For the 1997 Women's Cricket World Cup, Terblanche continued as wicket-keeper, but was promoted to open the batting alongside Linda Olivier in all but two of the matches. She finished the tournament with 124 runs, second amongst the South Africans only to Olivier.[7] Against Denmark, she shared a 102 run first-wicket partnership with Olivier to help set up a 99 run victory for South Africa.[8]
Three years later in the 2000 Women's Cricket World Cup, Terblanche once again trailed only Olivier in the South African's batting charts, and courtesy of 3 not outs, she had the superior batting average, her 200 runs coming at 40.00.[9] She played a key-role in securing a semi-final berth for South Africa, playing a strong supporting role in a five-wicket victory over England, her 41 runs coming off 117 runs.[10] She hit her maiden half-century in the fourth group match, played against Sri Lanka, remaining not out as the team won by six wickets.[11]
After defeat in the World Cup semi-final, South Africa didn't play another international match for over a year, when they hosted India. Following the retirement of Olivier, South Africa struggled to score runs, with Terblanche managing just 64 in her four innings.[12] Despite this, South Africa won the one day series 2–1, and then played their first Test match since 1972. In a four-day match, Terblanche scored 25 & 2 as South Africa chased 404, eventually losing by 10 wickets.[13]
