  • Busy hours = 7.00pm to 11.00pm.
  • Busiest hour = Fifth lowest hourly average speed out of all the month's busy hours for each RSP. The busiest hour calculation method was revised in May 2019. Busiest hour results are not comparable with those published in Feb 2019.
  • = Benchmark level 60%.
  • +- Percentage point changes compared with previous quarter's measurements.
  • Percent of maximum plan speed.
  • The shaded area indicates the boost to average speed if services not able to achieve maximum plan speeds were excluded from the overall results. These services include NBN FTTN connections not capable of delivering 50 Mbps. If you are a customer on a service that does not deliver expected speeds, contact your provider to ask whether the problem can be fixed or about moving onto a cheaper plan.

Average daily outages per user lasting longer than 30 seconds

  • All results
  • Excluding results that are unable to achieve maximum plan speeds
  • Note: This excludes outages between midnight and 6am when maintenance and upgrades are usually carried out.

NBN and ADSL plan speeds delivered during busy hours by technology

  • All results
  • Potential speeds that could be delivered when excluding results that are unable to achieve maximum plan speeds

Average NBN and ADSL download speeds during busy hours by plan

Average NBN and ADSL download speeds by hour of day

Distribution of download speed tests, by percentage of plan speed

  • This chart shows the proportion of download speed test results for NBN plans that were above 90 per cent of plan speed, between 50 per cent and 90 per cent of plan speed, and under 50 per cent of plan speed. ADSL results are excluded.

Technical quality measures

Technical quality measures includes web page loading time, latency, and the frequency of packet loss.
