Gamers spent more than 14 hours per week on average engaged in the pastime.
That's according to new data compiled by Accenture and commissioned by NBN Co.
For one-in-seven users, gaming was one of their most important online activities, and one-in-10 say it is the most important.
Researchers also found gaming isn't just a source of entertainment, it also helps connect people.
Additional data from the Interactive Games and Entertainment Association shows 43 percent of Australian parents play online games with their children.
Twenty-five percent of adult gamers also play with their partners online and more than a quarter share videos of their gameplay online.
NBN customers told Accenture they expected to increase their gaming time by up to 50 percent per year through to 2028.
Three in four were reliant on NBN during COVID-19 to access forms of entertainment or relaxation while about 14 percent who upgraded their plan during the pandemic did so to support online gaming.
COVID led many NBN users to spend an extra hour a week using online entertainment, including gaming.
