The generations of Australians who entered adulthood in the second half of the twentieth century experienced a standard housing tenure trajectory that was more clearly defined than it is today. Young adults would typically leave the family home to marry and await the birth of their first child while residing in a rental home before entering into home ownership. The housing tenure trajectories of later generations who entered adulthood closer to the turn of the twenty-first century have become destandardised, but there is little empirical analysis of these trajectories or their consequences.As time progressed towards the turn of the twenty-first century, the standard life course trajectory was challenged by the concept of 'choice', which led to the loosening of traditions and a more diverse range of lifestyles. Many of these changes were associated with changing life course patterns, for example, individuals were spending more time in further education, delaying entry into the labour force, entering unions that may or may not result in marriage and choosing to postpone the birth of a first child. Early literature assumed that there was an appropriate order and timing for transitions of key life-events and that negative outcomes would be experienced later in life if an appropriate sequence of housing tenure and family events was not adhered to. Specifically, the age pension at retirement in Australia assumes low housing costs which have long term implications for families that do not attain home ownership, increasing their vulnerability to poverty in the later stages of life.This thesis draws on longitudinal data from the first ten waves (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)
