Comparisons across survey cycles
The proportions of Aboriginal and Torres Strait Islander people who always use the same source of health care, and those who do not always use the same source of health care, have remained relatively stable across survey cycles (Figure 16). From 2012–13 to 2018–19, the proportion of those who always used the same source had a slight but significant increase from 80% (or an estimated 509,000 of 637,000) to 85% (693,000 of 814,000), before decreasing to 83% (830,000 of 994,000) in 2022–23.

Notes:
- Data are population weighted estimates.
- While non-overlapping confidence intervals (CIs) generally indicate statistical significance, overlapping CIs do not necessarily imply that a difference is not significant. See Technical notes for more information.
