Ambulance Code 1 Response Time — Methodology and Sources
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:
| FY | Vic 90th percentile (min) | ROGS release |
|---|---|---|
| 2014-15 | 22.1 | 2023 |
| 2015-16 | 21.5 | 2023 |
| 2016-17 | 20.5 | 2023 |
| 2017-18 | 19.1 | 2023 |
| 2018-19 | 18.0 | 2023 |
| 2019-20 | 18.7 | 2023 |
| 2020-21 | 21.6 | 2023 (matches 2026) |
| 2021-22 | 26.6 | 2023 (matches 2026) |
| 2022-23 | 28.8 | 2026 |
| 2023-24 | 26.9 | 2026 |
| 2024-25 | 27.2 | 2026 |
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.
