The ACCC's third Measuring Broadband Australia report, released on Monday, shows that TPG Telecom was the fastest, followed by Aussie Broadband, iiNet, Optus, Telstra and MyRepublic.
Aussie Broadband took top spot in the second report, with TPG third, and iiNet, part of the TPG stable, second.
The report, prepared by UK outfit SamKnows, found that 69% of all tests recorded download speeds that were more than 90% of plan speeds. Only 7% of tests recorded speeds that were less than half of the plan maximum.
“We encourage customers who aren’t getting the speeds they expected to contact their internet service provider to see if they need to change plans. We will continue to closely monitor the progress of industry in remedying this issue.”
Broadband speeds did not slow down a great deal during the busy hours - 7pm to 11pm - with average speeds falling by 11 percentage points compared to the average.
“We are pleased that the Measuring Broadband Australia program is being taken very seriously by ISPs and is delivering noticeable improvements to customers’ broadband speeds,” Sims said.
“We note NBN Co has reported that congestion has increased slightly in recent months. Our results suggest that ISPs not featured in this report could be contributing to this, as the overall results featured in this MBA report do not show an upward trend in congestion.
“We want to encourage consumers, particularly those with smaller ISPs, to register their interest in the program so we can provide statistically significant results for a wider range of services.
“Volunteers are making a real difference to Australia’s broadband performance but we don’t yet have the full picture, and strongly encourage more people to sign up.”
Testing of 25, 50, and 100 Mbps plans and ADSL services was carried out in August and involved 950 NBN and ADSL services supplied by 15 ISPs, using 171,000 download speed tests. The results are statistically significant with a small sampling error.
