Karratha Christmas Island

Christmas Island and Karratha are very different places. Christmas Island is far more diverse, with 43.7% of people born overseas and 44.7% using a language other than English at home. It also has a much older First Nations population, with a typical age of 60. Karratha is more affluent, with 49% of households earning $3,000 or more a week compared to 28% on Christmas Island. Karratha also has a much higher share of people who are not religious, at 47.8%, while only 19.9% of people on Christmas Island identify this way.

Both areas are similarly car-dependent and have seen almost identical population growth of about 10% since 2021. They also share similar rates of full-time employment and volunteering. While some gaps are closing, such as the difference in rental rates and the share of people born overseas, others are widening. For example, the gap in the number of people aged 65 and over has grown, as Karratha's population remains far younger than that of Christmas Island.
