WASHINGTON — SingTel of Singapore said March 18 it has hired two investment banks to review a possible sale of the SingTel-owned Optus Satellite of Australia, which SingTel said it wants to sell to optimize value for its shareholders.

Industry officials attending the Satellite 2013 conference in Washington speculated that APT Satellite of Hong Kong, partly owned by ChinaSat, and Eutelsat of Paris both would be potential bidders for the Optus assets, which include five satellites in orbit and one satellite under construction.

Optus reported revenue of 319 million Australian dollars ($330 million) for the fiscal year ending March 31, 2012.

SingTel said Optus’s broadcast customers include the Australian Broadcasting Corporation., Foxtel, GlobeCast Australia, SBS, Southern Cross, WIN, GWN7, NBN Co., New South Wales Department of Education and Communities, Department of Defence and Air Services Australia.
