But high speed Fibre-to-the-Node services under-performed in tests by the Australian Competition & Consumer Commission found.
Fixed-line NBN users received an average of 86.6 percent of the maximum possible download speed available on their plans during tests by the Australian Competition & Consumer Commission (ACCC).
That was a positive result according to the ACCC, which stated that it shouldn't be interpreted as NBN providers failing to provide the speed they advertised.
The ACCC tested 1,212 fixed-line NBN connections during November 2019, and has published the results in the new Measuring Broadband Australia report.
The tests found a 1.2 percent improvement in average fixed-line NBN download speeds since the ACCC's previous broadband speed report.
Between 7pm and 11pm, fixed-line NBN connections achieved an average of 85.3 percent of their maximum possible download speeds.
During the evening, users on 100/40Mbps NBN plans saw the biggest drop in download speeds. Between 5pm and 9pm, their speeds dropped an average of 5.8 Mbps below their maximum day's speed.
Report card not as good for high speed Fibre-to-the-Node
But the ACCC is critical of NBN Fibre-to-the-Node (FTTN) services. “Too many” FTTN users aren’t getting speeds they pay for, ACCC Chair Rod Sims stated.
About a quarter of FTTN users with 50 Mbps and 100 Mbps plans didn’t receive “anywhere near” their full plan speeds, the report states.
“We are pleased to see that speeds have generally improved, however we need more action from NBN Co and retail service providers so that all consumers can access their full NBN plan speeds,” Sims stated.
NBN outperforms ADSL
Fixed-line NBN outperformed ADSL in the ACCC’s tests. In the evenings, users on 12 Mbps NBN plans recorded an average download speed of 10.8 Mbps, while ADSL users recorded an average speed of 7.7 Mbps.
Fixed-line NBN connections tested by the ACCC had less outages, lower latency and less packet loss than ADSL connections.
The ACCC is seeking more volunteers to join its NBN speed testing program – particularly Dodo, iPrimus and MyRepublic customers and people living in new housing estates with fibre broadband services.
NBN complaints fall
Meanwhile, complaints to the Telecommunications Industry Ombudsman (TIO) about NBN fault and connection problems have decreased.
The TIO reports that complaints about NBN Internet service faults and connections fell from 4,619 in the first quarter of 2019-20, to 3,740 in the second quarter.
The number of complaints to the TIO about NBN telephone services also fell during the same period, from 1,826 to 1,481.
