Coetzee made his Twenty20 debut for Gauteng in the 2018 Africa T20 Cup on 14 September 2018.[4] He made his first-class debut for Gauteng in the 2018–19 CSA 3-Day Provincial Cup on 4 October 2018.[5]
Coetzee's career in South Africa stalled in 2019 after he was released from his provincial contract.[2] Contemplating retirement, he relocated to Hong Kong for non-cricketing reasons when his wife accepted a teaching position.[2] He initially intended to play cricket only recreationally.[2]
Upon joining the Hong Kong Cricket Club, he discovered a highly organized and competitive local cricket scene with a clear pathway to international representation through a three-year residency qualification.[2] This inspired him to pursue a career with the national team. After completing his residency, Coetzee established himself as a top-order batter for Hong Kong.[2] Outside of his national duties, he works as a professional coach.[2]
