Faster Internet speeds for Aussies connected to the NBN network are coming this Sunday. 50Mbps services will increase to 100Mbps, and for FTTP or HFC services, 100/20Mbps will increase to 500/50Mbps and 250/25Mbps will increase to 750/50Mbps. The new 2Gbps service will also be available, however in most cases this will require an updated NTD device from NBN.
