Vlaeminck was raised in Bendigo, where she played both cricket and soccer. After taking the field for the Northern Rivers region in the under-14 girls state cricket championships, she joined the Victorian Under-14 team. Before long, she was selected in the Under-18s. As a 15 year old, she came close to quitting cricket in favour of soccer, but was persuaded to keep playing.[2][4]
In early 2015, Vlaeminck ruptured her anterior cruciate ligament. Just two matches after completing a full recovery and rehabilitation program, she suffered a second ACL injury, in the form of a partial tear. On advice from a surgeon, she kept playing for two months, including for the Victorian Under-18s, until the ACL ruptured again.[2][4]
Prior to the 2017–18 WNCL season, Vlaeminck was selected for Victorian Spirit. During her WNCL debut, against the ACT Meteors at Manuka Oval in October 2017, she took the new ball; her 2-34 off seven overs included the wickets of Dane van Niekerk and Nicola Hancock.[5] A month later, she played for the Cricket Australia XI in a tour match against England.[6]
In late November 2017, Vlaeminck dislocated her shoulder playing another match for Victoria. That injury prevented her from playing for the Renegades in WBBL|03. However, she then played well enough in two further matches for Victoria to be selected for the Australian Under-19 tour of South Africa in March 2018. A bout of glandular fever almost prevented her from joining that tour, but after a low key start, she captured 5–32 in 6.5 overs against South Africa in Pretoria. In the series final, also against South Africa, she took a match-winning 6–27 in 7.5 overs.[2]
In April 2020, Cricket Australia awarded Vlaeminck with a central contract ahead of the 2020–21 season.[21][22] In January 2022, Vlaeminck was named in Australia's squad for their series against England to contest the Women's Ashes.[23] Vlaeminck played the first match in the series against England, before suffering another stress fracture leading up the 2022 Women's Cricket World Cup. The injury caused her to miss both the World Cup and the Ashes.[24]
In June 2023, eighteen months after her last international match, she was selected to play for Australia A against England A, for their series along the Women's Ashes. She played four matches, taking a wicket in each, before picking up a left shoulder injury in the last 50-over match.[25] She was later ruled out of the 2023–24 Women's Big Bash League.[26]
She was named in the Australia squad for the 2024 ICC Women's T20 World Cup[27] but suffered a shoulder injury in the group match against Pakistan and was ruled out of the rest of the tournament.[28]
