The Millennial Mountain — Why 7 Million Aussies Are About to Rewrite the Housing Market

For twenty years, the story of Australian housing was apartments. Cranes over the CBD, young professionals in one-bedroom towers, cafes on every corner. 

 Today, that story is quietly ending, and almost nobody in property or planning has caught up with it yet.  

The generation that built the apartment boom is now the generation walking away from it, and where they go next is going to reshape entire suburbs.  

Australia’s largest generation is entering a new stage of life, and that is going to change what millions of people want from their homes. 

In this episode Simon Kuestenmacher and I explain how Australia’s largest generation is reshaping housing demand. 

By the end of this episode, you’ll know exactly which property types are about to come into serious demand, and which ones risk being left behind. 

We explore why millennials are moving from inner-city apartments towards larger homes with bedrooms, storage, outdoor space and room for hybrid work. 

We discuss how the “Millennial Mountain” is influencing consumer behaviour, family formation, property preferences and future urban development. 

We examine why Australia’s missing middle remains difficult to deliver, despite growing demand for townhouses, duplexes and medium-density housing. 

We consider what demographic change, intergenerational wealth transfers and shifting suburb preferences could mean for property investors over the coming decades.

  • Parental wealth increasingly affects home ownership access
  • Middle suburbs may face future density pressure
