NBN broadband services from iiNet, Optus, Telstra and TPG are delivering between 80 and just over 90 per cent of the maximum plan speeds in the evenings, a new ACCC report has found.\nThe analysis is part of the ACCC\u2019s Measuring Broadband Australia program, which found that these \u2018busy hour speeds\u2019 between 7pm and 11pm are now only marginally below typical speeds at other times.\nIn April last year, the government said it would fund the ACCC to roll out an independent national broadband performance monitoring and reporting program to provide consumers with accurate reporting about speeds through to 2021.\nThe $6.5 million monitors residential fixed broadband speeds, reaching a maximum of 4000 Australian homes in its final year, publishing results periodically.\nACCC chairman Rod Sims said the first test results are better than expected and indicate the majority of ISPs are now delivering very close to their maximum plan speeds. But 5 per cent of services tested operated at less than 50 per cent of their maximum plan speeds.\n\u201cThe results for some types of services are still lower than we would like, but the overall results go against the current wisdom that the majority of consumers and businesses are having issues with NBN speeds,\u201d Sims said. \nHowever, the relatively high speeds during peak periods indicated that retailers are now providing enough network capacity to meet the demand in peak usage periods, including on the top speed plans, he said.\nLast week, Vocus brands Dodo, iPrimus, and M2 Commander said they would compensate customers over NBN services speed claims. This came after TPG subsidiaries iiNet and Internode agree to compensate 11,000 customers over NBN speed claims.\nSims said the results of the ACCC report reflected changes in the market, particularly the recent discounting by NBN Co of capacity charges and consequent take up of more CVC by retailers.\n\u201cThey likely also reflect the effect of our speed advertising guidelines and anticipation that our testing was soon to begin. It is highly likely that just a few months ago these results would not have been anywhere near as good,\u201d Sims said.\nFour hundred 25Mbps, 50Mbps and 100Mbps NBN and ADSL services took place in February and March 2018. They were supplied by 10 ISPs, reflecting 61,000 individual download speed tests.\nThe report found that four major providers \u2013 iiNet, Optus, Telstra and TPG \u2013 deliver download busy hour speeds of between 88.1 per cent and 90.7 per cent of maximum plan speed.\nIt also found that NBN 25Mbps plans, the standard to which NBN is instructed to build broadband services, significantly outperformed ADSL services. The average ADSL speed is 8Mbps compared with an average of 22-23Mbps for NBN 25Mbps plans.\nFTTN connections that could not support the maximum plan speed were a factor that brought down the average speeds overall. The ACCC said it expects averages will improve further as service providers act on court-enforceable undertakings and adopt the ACCC advertising guidance to ensure customers are provided with plans that do not exceed the maximum attainable speeds of their individual connection.
