The competition was played between the thirteen South African provincial teams. In previous editions of the competition, Namibia had also competed. However, in October 2018 they withdrew from South Africa's provincial competitions, citing issues around costs and logistics.
Unlike its counterpart, the CSA Franchise 4-Day Cup, the matches were three days in length instead of four. The tournament was played in parallel with the 2018–19 CSA Provincial One-Day Challenge, a List A competition which featured the same teams. KwaZulu-Natal were the defending champions.
Eastern Province and Northerns contested the final, which finished as a draw, therefore the title was shared.
