Both Optus and Telstra will launch the Galaxy S III 4G in Australia but the big news is that the Samsung Galaxy S III 4G will be the first smartphone to launch on the new Optus 4G network.

According to the telco, Optus 4G coverage stretches up to 10km from Sydney's CBD to cover suburbs like Port Botany and Chifley in Sydney's south, Brookvale and Dee Why north of Sydney, Vaucluse and Bondi Beach in the east and Silverwater and Homebush in western Sydney. The 4G network will also service Newcastle, including areas like Maryland, Edgeworth and Cessnock, and will stretch up to 15-20km from the Perth CBD in Western Australia.

The new Optus 4G network promises download speeds of up to 50Mbps, which is around seven times faster than what you can achieve on a 3G networks. To put these speed claims to the test, we managed to get our hands on one of the first Samsung Galaxy S III 4G smartphones in the country at the Optus store on George Street, Sydney.

In general, 4G data download speeds ranged from just under 20Mbps to just over 26Mbps, while upload speeds ranged from just under 6Mbps up to almost 9Mbps.

As you can see, the Galaxy S III 4G had between two and four bars of 4G reception during our test. Also keep in mind that with the Optus 4G network only launching today, network congestion is minimal. As more people use the network, you can expect speeds to vary.
