Every figure in K-Stra sits on a map: official areas for reporting, single addresses for counting, and roads for travel times. In short K-Stra divides Australia into nine ABS administrative levels, from the whole country down to 61,844 SA1 areas, and below them into 14.5 million address points. Statistical areas follow the 2021 edition of the ABS geography and councils the 2025 one. A road network of 12 October 2026 gives travel times by car and on foot.

In the app ## How do I pick an administrative area in K-Stra? *[Image: The Where step of K-Stra on the Administrative tab, without an account: a search box, the list of Australian states with their residents, and the choice of the level shown on the map.]* No account needed Where · AdministrativeSearch a state, region, council or postcode by name, or walk down from the states. The map shows the level you pick, or follows the zoom. The Where step has three ways to set an area: a location with drive or walk times, a shape drawn on the map, or administrative areas. The third lists every state with its residents and lets you walk down level by level or type a name. Clicking the name of a council on the map opens its free dashboard. Picking areas, browsing them and reading their dashboards costs nothing; credits are spent only when an analysis runs on them. Addresses and roads ## Why does K-Stra count addresses instead of areas? A drive time never follows official boundaries. Of the 14.5 million address points, 8.9 million have residents; each carries its share of the area’s population, so a catchment adds up exactly the addresses it reaches and its edge falls between two street numbers. Travel times come from a road network rebuilt on 12 October 2026: by car, by car avoiding motorways, or on foot, in average or heavy traffic. Each address is attached to the nearest road it can be reached from, so a house across a river is not counted as next door.

Editions ## What changes with the new ABS geography? Every five years the ABS redraws its statistical areas to follow population growth. Edition 4, for 2026 to 2031, came out in July 2026 for the main areas and in October 2026 for councils, postal areas and suburbs. Most of the change is in the smallest areas, where new suburbs have filled up: 1,640 more SA1 areas and 98 more SA2 areas. K-Stra keeps Edition 3 until the 2026 Census is published on the new areas, so that boundaries and census figures stay matched.

Because the 2021 Census data exist only on the 2021 areas. The ABS released Edition 4 of its geography between July and October 2026; K-Stra moves to it with the first results of the 2026 Census, from June 2027, so that areas and figures stay matched. ### Are postcodes the same as postal areas? Nearly. The ABS builds postal areas from small blocks to approximate the postcodes of Australia Post, and a few cross state borders. K-Stra uses the ABS postal areas, so figures can be checked against ABS tables. ### How many areas can one analysis cover? Up to 12 administrative areas of any level, mixed as you like, or up to 10 shapes drawn on the map. Drive-time and walk-time areas count the address points they reach, whatever the boundaries.
