The shadow ministry of David Speirs was the Liberal Party opposition between April 2022 and August 2024, opposing the Malinauskas government of the Labor Party in the Parliament of South Australia. It was led by David Speirs following his election as party leader and leader of the opposition on 19 April 2022, and lasted until Speirs resigned as party leader and opposition leader on 8 August 2024. The deputy leader of the shadow ministry was John Gardner.
The shadow ministry succeeded the Marshall ministry as the Liberal Party frontbench and the Malinauskas shadow ministry as the South Australian shadow cabinet. It was succeeded by the Tarzia shadow ministry.
The current Speirs shadow ministry was announced on 21 April 2022. The shadow ministry is made up of 15 members of the Liberal Party. Ministers from the previous Marshall ministry David Basham, David Pisoni and Stephen Wade opted to remain as backbenchers. Former deputy premier Vickie Chapman also opted not to return to frontbench after announcing her retirement from politics earlier in the week. There were a number of new additions to the Liberal Party frontbench, including Ashton Hurn and Penny Pratt who were newly elected at the election and immediately elevated to the frontbench.
