SingTel's Australian unit Optus said on Friday that it has successfully launched a state-of-the-art satellite into orbit.
The satellite, named Optus 10, was propelled into orbit following lift-off from the Guiana Space Centre in Kourou, French Guiana.
"This represents the next advance into space by Australians and is an exciting milestone for Optus," said Optus Wholesale and Satellite managing director Rob Parcell in a statement.
Optus launched Australia's first satellite almost 29 years ago. It is the only Australian company to own and operate satellites.
"Optus' satellite business holds a unique position - no other Australian telecommunications or satellite company can match the range of communications services we provide," Mr Parcell added.
"Our satellites reach every part of the country, delivering subscription and free-to-air television and radio services, as well as voice and internet for emergency service providers and mining and agricultural industries."
The Optus 10 satellite expands Optus' satellite fleet capacity and provides an in-orbit redundancy capability.
Optus has the largest fleet of geostationary satellites in the region, servicing Australia, New Zealand and the McMurdo Sound in the Antarctic.
"Today's launch demonstrates Optus' commitment to keeping Australia and New Zealand at the forefront of satellite technology as we continue to invest in bringing communications capability to more households," Mr Parcell said.
