Urban planning and the development system are mechanisms that can provide affordable housing and alleviate the cost of housing. This paper explores the use of a specific response to housing affordability and delivery of affordable housing in Queensland through the introduction of a statutory land authority, the Urban Land Development Authority (ULDA). It provides a narrative review of an important time in Queensland’s planning and development history. The introduction of the ULDA was significant as it represents the first time that Queensland planning saw the introduction of planning-related legislation that could require affordable housing. Even more extraordinary was that the deliverables (affordable housing) sat outside the mainstream planning legislation of the time. Additionally, the establishment of the ULDA represents the first statutory land authority responsible for planning and development in Queensland. While similar authorities have been operational in many States since at least 1974, this was never the case in Queensland, but the Queensland response of the ULDA was unique in Australia in terms of its powers and structure. This paper considers that despite such extraordinary powers, the outcomes of the ULDA were not as effective as originally anticipated.
