Serpentine Rottnest Island

Serpentine and Rottnest Island (L) are very different Western Australian locations. Serpentine is a residential area where families are common, with 21.1% of people being children and 93.6% of homes having three or more bedrooms. In contrast, Rottnest Island (L) is sparsely populated and largely non-residential, with many more people born overseas (39.8% compared to 18.1% in Serpentine) and a much higher share of renters at 54.1%. While Serpentine has many more households earning $3,000 or more a week (32.1%), Rottnest Island (L) has a more qualified workforce, with 24.8% of adults holding a bachelor degree or higher.

Since 2011, the two areas have moved in opposite directions across several measures. The gap in renters has narrowed, but the difference in housing types has grown as Serpentine's share of large, detached homes increased. Despite these shifts, they share a similar typical family income of around $2,400 a week and almost identical unemployment rates of about 3%. Both also lack easy access to most amenities, with virtually no homes within a 15-minute walk of health services or groceries.
