Group boundaries are determined by postcode using data from lochac.sca.org/groups and devices are from roll.lochac.sca.org. Some postcodes such as 0872 span multiple states and multiple groups. To handle these cases we split up the postcode by state and then use the state to determine the correct group in these cases. Group info last updated on 2026-01-28.

Australian state and postcode boundary data comes from the ABS and New Zealand postcode boundary data comes from github.com/s01ipsist/open_nz_postcodes.
