Optus is the best fixed-line internet service provider (ISP) in Australia for download speeds overall, while Telstra is the best during peak-hour times, when network congestion is at its highest.
Meanwhile, Telstra is the best for mobile data speeds overall, including during peak-hour.
That’s according to speed testing data from the second and third quarters of this year from Ookla, which operates speedtest.net, one of the internet’s most popular speed testing tools.
For fixed-line broadband, Optus came out on top overall as the “fastest” provider with an average download speed of 24.12 Mbps and average upload of 8.48 Mbps. It was followed by Telstra, TPG, iiNet, and iPrimus. During peak hour (7-11 pm), however, Telstra came out as the winner, with average download speeds of 21.96 Mbps and upload speeds of 7.70 Mbps.
