Ambulance Code 1 Response Time — Methodology and Sources

Last reviewed: 2026-05-18

What this measures

Statewide 90th-percentile response time (minutes) for Code 1 ambulance incidents in Victoria — i.e. the time within which 90% of urgent, time-critical Code 1 calls are responded to.

Lower is better. Ambulance Victoria's official target is 15 minutes for 90% of Code 1 cases statewide.

How values are derived

The Productivity Commission's annual Report on Government Services (ROGS) publishes Code 1 response times by state in Table 11A.5, sourced from the Council of Ambulance Authorities (CAA). The series here stitches two ROGS releases:

FYVic 90th percentile (min)ROGS release
2014-1522.12023
2015-1621.52023
2016-1720.52023
2017-1819.12023
2018-1918.02023
2019-2018.72023
2020-2121.62023 (matches 2026)
2021-2226.62023 (matches 2026)
2022-2328.82026
2023-2426.92026
2024-2527.22026

Overlapping years (2020-21 and 2021-22) match exactly across the two releases, providing a cross-check.

Reading the line

  • 2014–2019: gradual improvement from 22 to 18 minutes — the target (15) remained out of reach but the trend was healthy.
  • 2020 onward: response times jumped sharply during the COVID period and have stayed roughly 27 minutes since. That's nearly double the published target.
  • AV's quarterly performance reports show the percent within 15 minutes metric — the same underlying performance from a different angle (the figure has fallen from ~80% pre-COVID to ~65% post-COVID).

Caveats

  • 90th percentile is a single point — a few extreme outliers do not move it much, but a broad shift in dispatch performance does. It's the right measure for "what does a Code 1 caller actually wait?".
  • ROGS includes a separate Capital city slice with slightly different values; the line shown is the Statewide series.
  • "Code 1" definitions are nationally consistent across ROGS jurisdictions, so cross-state comparisons in the underlying table are apples-to-apples.
