In 1988 – the city's 200th anniversary – Carr, Wran's planning minister, released a new strategy, called "Sydney into Its Third Century". Though it emphasised continuity with the 1948 Cumberland Plan and the 1968 SROP, the 1988 plan represented a major change in strategy. Although Sydney's borders would continue to expand, principally to the west and south-west, the government would explicitly target higher urban density.
