CONSIDERING that, in accordance with the Commonwealth and State Housing Agreement Act 1945, the Commonwealth has concluded an agreement (referred to as the "Main Agreement") with the States with respect to housing, dated the nineteenth day of November, one thousand nine hundred and fifty, and which was to enter into force between the Commonwealth and each State after having been approved or approved by the Parliament of that State: Between 1956 and 1973, the main objective of the CSHA was to promote residential property through the granting of subsidized loans to home builders and the sale of houses on very advantageous terms. Public rental housing remained important, especially for low-income households who could not afford to buy a home. During this period, states had considerable room for manoeuvre under the CSHA (including the level of rents, the type of rebates, the eligibility criteria and even the amount of funding), which led to significant political and financial disparities between the different legal systems. The 1978 Convention continued to limit housing assistance to the poorest – subsidies were provided to help pensioners and others in need. The agreement also provided for an extension of the types of housing provided under the CSHA, including the rental of housing, joint ventures, collective housing and interest subsidies for those who buy a house. In the 1978/79 budget, the Commonwealth required states to adapt the progress of the Commonwealth CSHA. Article 96 of the Constitution, which authorizes the federal Parliament to "provide financial assistance to each state on such terms as Parliament deems just," was the legal route by which the Commonwealth made CSHA funds available to states and territories to enable the construction of social housing and the provision of funds for the purchase of houses. .
