How long people wait to be seen in emergency departments (EDs) is a measure of the accessibility of ED care.
Waiting times measure the time elapsed from presentation in the ED to commencement of clinical care.
Over the last five years, the proportion of patients ‘seen on time’ has decreased and the time in which 90% of presentations were completed has increased.
Measurement of time in the emergency department
Progress of the patient through the ED is recorded using 5 different time points:
- Presentation time—the time of first recorded contact with an ED staff member, which may be at the start of clerical registration or of the triage process.
- Triage time—the time at which the patient was assigned a triage category, which can coincide with presentation time.
- Clinical care commencement—the time at which care by a doctor, nurse, mental health practitioner or other health professional commenced, which can also coincide with presentation time.
- Episode end time—the time at which the non-admitted patient ED service episode ended.
- Physical departure time—the time at which the patient departed the ED, which can coincide with episode end time.
These time points are used to derive the patient’s waiting time, the duration of clinical care, and the length of the emergency department stay.
Emergency department (ED) waiting time is the time elapsed for each patient from presentation in the ED to commencement of clinical care.
A patient is considered to have been 'seen on time' when the time between arrival at the ED and the time that their clinical care starts is within the time specified in the definition of the triage category they are assigned:
- Resuscitation: Immediate (within seconds)
- Emergency: within 10 minutes
- Urgent: within 30 minutes
- Semi-urgent: within 60 minutes
- Non-urgent: within 120 minutes.
Explore the data
The data visualisation below presents the following emergency department waiting time statistics by triage category:
- proportion seen on time
- 50th percentile (median) waiting time (half of all people waited less than this time)
- 90th percentile waiting time (90% of people waited less than this time).
In addition to the national data, the data can also be explored for recent years by:
- state and territory
- hospital (where data is available)
- local Hospital Network (LHN) (where data is available).

National, state and territory data are available. In 2022–23, 65% of patients were seen on time, compared with 71% in 2018–19.
Hospitals and LHNs
This figure explores waiting times in emergency departments between in 2013–14 and in 2022–23. Data is presented by measure (number of patients presenting to the ED and the percentage of patients who commenced treatment within the recommended time), triage category and peer group. Hospital, Local Hospital Network (LHN), national, and state and territory data are available.
Highlights
Over the last five years, the proportion of patients ‘seen on time’ has decreased and the time in which 90% of presentations were seen has increased.
In 2022–23:
- the proportion of patients ‘seen on time’ was 65%, down from 67% in 2021–22 and from 71% in 2018–19
- Principal referral and Women’s and children’s hospitals and Public acute group A hospitals had the lowest overall proportion of presentations ‘seen on time’ (61%), and Other hospitals had the highest proportion (92%)
- 50% of patients were seen within 20 minutes, consistent with the previous year and higher than the preceding three years
- the time within which 90% of presentations were seen was 2 hours and 4 minutes, an increase from 1 hour and 40 minutes in 2018–19.

Emergency department (ED) waiting time is the time elapsed for each patient from presentation in the ED to commencement of clinical care.
Waiting time statistics are presented as the:
- proportion seen on time
- 50th percentile (median) waiting time (half of all people waited less than this time)
- 90th percentile waiting time (90% of people waited less than this time).
Explore the data
In the data visualisation below, you can explore 2022–23 ED waiting times by the patient’s Indigenous status and remoteness area of usual residence.
Comparisons of ED waiting times by Indigenous status and remoteness area of the patient's usual residence should take into account that not all hospital emergency services provided in Australia are included (only those services that are provided through an emergency department that meets specific criteria), and the number of hospitals reporting to the collection varies by remoteness of the hospital.
Waiting times by demographics
All data in these visualisations are available for download in the Data & downloads section of the MyHospitals website.
Indigenous status
This column graph shows the waiting time statistics (proportion seen on time, median (50th percentile) waiting time and 90th percentile waiting time) for emergency presentations in 2022–23. Data is presented by Indigenous status. National, state and territory data are available. In 2022–23, Indigenous Australians had a slightly higher proportion seen on time compared with Other Australians across all triage categories except Resuscitation.
Remoteness area
This column graph shows the time waited by 50% of patients by remoteness area of usual residence in 2022–23. Data is presented by triage category. National data is available. In 2022–23, time waited by 50% of patients varied by remoteness area of usual residence; ranging from 21 minutes for patients living in Major cities to 17 minutes for patients living in Outer regional areas.
Highlights
Variation by Indigenous status
- Nationally, in 2022–23, the proportion of presentations for First Nations people who were seen on time was 67%, which was slightly higher than for non-Indigenous Australians (65%).
- First Nations people had same median waiting time (20 minutes) as non-Indigenous Australians (20 minutes).
- For the Urgent and Non-urgent triage category, Indigenous Australians had a shorter median waiting time (22 minutes) than non-Indigenous Australians (24 minutes).
Variation by remoteness of area of usual residence
- Median waiting times for emergency department presentations were longest for people living in Major cities (21 minutes) and shortest for those living in Outer regional areas (17 minutes).
- The largest differences in median waiting times across remoteness areas occurred for presentations assigned a triage category of Non-urgent – for these patients median waiting times varied from 16 minutes for patients living in Outer regional areas to 30 minutes for patients living in Major cities.
- Patients living in Major cities had the longest median waiting times for Emergency (8 minutes), Urgent (25 minutes), Semi-urgent (35 minutes) and Non-urgent (30 minutes) triage categories.

An emergency department (ED) stay is the period between a patient presenting at an ED, and when that person is recorded as having physically departed the ED (regardless of whether they were admitted, referred, discharged or left at their own risk).

- 90% of ED presentations were completed within 10 hours and 32 minutes which is just over 3 hours longer than in 2018–19 (7 hours, 29 minutes)
- the time in which 90% of patients completed their ED care was longer for patients who were subsequently admitted to the hospital (18 hours, 23 minutes) than for patients who were not admitted (7 hours, 19 minutes)
- 56% of patients who presented to ED had their care completed within 4 hours compared to 61% in 2021–22 and 70% in 2018–19
- for patients subsequently admitted to the same hospital, one-third (31%) of ED presentations were completed within 4 hours
- for patients not subsequently admitted, two-thirds (66%) of ED presentations were completed within 4 hours
- 79% of ED presentations occurred between the hours of 8 a.m. and 10 p.m.
