This book explores the decline and growth of the private rental sector in Australia delving into the changing dynamics of landlord investment and tenant profile over the course of the twentieth century and into the present period. It explains why over one in four Australian households are now private renters and investigates the contemporary legal and regulatory frameworks governing the sector. The reform discourses in Australia and comparator countries, and debates around key concerns such as Australia’s advantageous tax treatment of investors in rental property and the power imbalance between tenants and landlords are highlighted. The book draws on rich data: 600 surveys and close to 100 in-depth interviews with tenants in high, medium and low rent areas in Sydney and Melbourne and regional New South Wales. The book provides in-depth insights into this large and expanding component of Australia’s housing market and shows how being a private renter shapes the everyday lives and wellbeing of people and households who rent their housing including short and long-term renters, those on low and higher incomes and older as well as younger people.
