Steele Hall Liberal and Country League Don Dunstan Labor State elections were held in South Australia on 30 May 1970.

However, the LCL's grip on the country areas was such that it was able to retain power when it lost by substantial margins in terms of raw votes.

Hall was embarrassed that his party was in a position to win power despite finishing seven points behind Labor on the two-party vote.

A 1968 Millicent by-election was triggered by the Court of Disputed Returns where Labor had won the seat by a single vote at the 1968 election.

Constituent anger forced Stott to vote against the Hall government, leading to an early election and the expected loss to Labor.

Hall remained Leader of the Opposition for two years before resigning from the LCL, claiming that the Party had 'lost its idealism [and] forgotten...its purpose for existence'.
