Australian wireless provider Boost Tel Pty Limited offers mobile service under the Boost Mobile brand. Up until January 21, 2013, Boost branded services were provided by the Optus network. Optus has licensed the Boost brand since the brand's launch in 2000.
In 2012, Optus decided to end its business relationship with Boost Tel Pty Ltd. In response, Boost entered into a deal with network competitor Telstra. After 20 January 2013, all existing Boost customers will be converted to Optus customers and will continue to receive services on the Optus network. On March 7, Boost Tel Pty Ltd. began to offer products and services under the Boost Pre-paid Mobile brand as an MVNO hosted on the Telstra Next G network.
Boost Mobile in New Zealand was a subsidiary of Telecom New Zealand. The Boost Mobile brand was discontinued in New Zealand as of November 2007.
