Build more houses. That'll fix Australia's housing crisis won't it?  If you listen to governments, you'd sure think so. Under the National Housing Accord, all governments have agreed to support a target of building 1.2 million new, well-located dwellings in 5 years.  But will that increase housing affordability, availability, quality, security of tenure, and the growing gap between the haves and have-nots? What's missing from this picture? Join Big Ideas host Natasha Mitchell at the 2025 National Housing Conference with guests debating the rhetoric, reality and policies around housing supply. This event was organised by the Australian Housing and Urban Institute (AHURI), hosts of the National Housing Conference.
