The Queensland Government Wireless Network (referred to as the GWN) is a trunked radio system operating in the state of Queensland, Australia. The network was built and is currently managed by Telstra under contract. The network commenced operation in 2014, and was operational for the 2014 G20 summit in Cairns. Following that event, the network was re-purposed and is now the main communications network for emergency services in South East Queensland.
