Subsidiaries
A number of notable wholly owned subsidiaries operate in Australia as part of the SingTel Optus group. These are:
- Information Technology & Network Services
- Alphawest
- Uecomm
- Mobile Telephony
- SIMplus
- Virgin Mobile Australia
Optus also sells mobile services under the brand name Boost Mobile.
Optus also has a 50% stake in the now defunct OPEL Networks.
Other wholly owned subsidiaries of note no longer have a significant active role as individual entities. These are as follows:
Reef Networks was formed in 1999 to provide an optical fibre link between Brisbane and Cairns. Optus gained exclusive access to this link in 2001, ahead of acquiring the organisation in 2005.
XYZed was established by Optus in 2000 to provide wholesale business-grade DSL services under an individual brand, but today provides a collection of products only as part of the Optus Wholesale & Satellite division. XYZed established a network of DSLAMs inside Telstra telephone exchanges, utilising Unconditioned Local Loop services to reach end users.
