The Huawei Wi-Fi network at Metricon Stadium - home of the Gold Coast Suns AFL team - will provide free, simultaneous access for a full house of 27,500 spectators.
The completion of the project was marked by the release of the Metricon Stadium app for Android.
"The stadium app is a great win for Metricon Stadium, the Gold Coast Suns and importantly, our guests," said Gold Coast Suns CEO Andrew Travis.
Other features include the submission of photos for display on the stadium screens, and additional capabilities are planned.
Huawei Australia chairman John Lord said "Following successful deployments of Huawei's Agile Stadium Solution in Europe, we are very proud Metricon is our first stadium in Australia and has now become the first fully connected smart stadium in Queensland."
Notable deployments in Europe include Signal Iduna Park (Borussia Dortmund; capacity over 81,000) and Amsterdam Arena (Ajax Amsterdam; capacity over 53,000).
"These are exciting times for Gold Coast Suns fans as our high performing and high-density Wi-Fi network provides excellent service for tens of thousands of spectators and reaches speeds far beyond the industry average," added Lord.
