Children may be leaving social media but broadband downloads are rising in Australia, and Queenslanders continue to use more data than users in any other state or territory.
NBN Co released details about Australia's online behaviour on Friday, also revealing downloads were expected to dip at the end of the 2025 but peak again in January.
The findings come after a year of change for internet connections in the nation, with thousands more households offered free speed upgrades and fibre to replace copper technology, as well as growing competition from satellite providers such as Starlink.
The reforms have encouraged more people to stream entertainment, NBN Co chief technology officer Guy Scott said, with the trend now using 48 per cent of all data downloaded from the National Broadband Network.
By 2035, the company predicts streaming video will account for 59 per cent of all NBN downloads.
Children were a major source of streaming demand as downloads were expected to peak during the school holidays, Mr Scott said, even though adults streamed content consistently.
"When the kids are off school, the network tends to get busier - in April, July, September and January, they're all busy times for us," he told AAP.
"What doesn't change is the busy hour - the busy hour stays consistently between 9pm and 10pm."
By contrast, the NBN expected to see a dip in downloads on New Year's Eve, he said, the time of its lowest daily peak demand.
More than three in four Australian households (76 per cent) use streaming video services, according to Worldpanel ComTech, with Paramount+, Stan Sport and ad-supported subscriptions growing in 2025.
In the other direction, broadband uploads continued to be dominated by communications platforms such as Microsoft Teams and Zoom during 2025, NBN Co reported, which made up 24 per cent of traffic.
Uploads over the NBN grew by 12 per cent during 2025, while downloads jumped by 10 per cent to reach an average of 508 gigabytes a month - twice the data downloaded in 2019.
Queenslanders downloaded the most data on average for the third year in a row, followed by Western Australia and the ACT, while Tasmanians downloaded the least data.
Download speeds also increased across Australia during 2025, fuelled by the NBN's free speed tier upgrades for 2.7 million users in September and free fibre upgrades for eligible premises from January.
About 12,000 households were moving to faster and more reliable fibre connections each week, Mr Scott said.
"We absolutely expect to see traffic continuing to grow," he said.
"We've built out the fibre network now to 3.5 million premises and we've got another 622,000 premises to build between now and 2030."
Australia recently ranked 42nd in the recent Ookla Research global broadband speed tests - above the United Kingdom for the first time, and up from 82nd place in February.
