Overview of Telstra

Telstra is one of the historic telecommunications providers in Australia. Telstra was originally founded in 1975 as the Australian Telecommunications Commission which was a government-owned, domestic telecommunications subdivision of the Postmaster General’s Department. The Australian Telecommunications Commission merged with the Overseas Telecommunications Commission in 1993, and in 1995 was uniformly branded as Telstra.

Between 1997 and 2011, Telstra slowly became more and more privatized, in stages, as the Australian government sold off its shares. With more than one million shareholders now, Telstra is one of the most widely held companies on the ASX.

Telstra is one of the biggest owners of fixed-line infrastructure in Australia, and much of the hybrid fibre-coaxial network technologies used by the NBN are from Telstra's HFC network. Telstra owns 51% of the NBN market share as of 2018, and together with Optus and TPG these three telecom companies own 83% of the total NBN market.

Telstra’s mobile network is one of three available in Australia, alongside Optus and Vodafone.

Telstra coverage in Australia

Telstra Coverage Map
Telstra Coverage Map

Telstra is one of the biggest network providers in Australia, covering 99% of the population with 3G and 4G coverage. The majority of their coverage is centered around the east and west coasts, but they do offer more coverage than other network providers in the Northern Territory.

Telstra is currently rolling out both 4GX and 5G coverage in small pockets, across major cities in Australia. By 20204, Telstra plans to suspend all 3G network availability with plans to establish 4G coverage in all areas currently covered by 3G. Telstra's new 4G coverage will be similar in reach and size as their current 3G network. After the switch, you will need a 4G-enabled phone in order to continue to access the Telstra Mobile Network. 

Telstra mobile phone plans

No matter what type of mobile phone plan you want, Telstra has it available. With Telstra prepaid mobile phone plans, you can choose the length of expiry period and amount of data and calls you want, while you can opt to contract a new phone and mobile plan with their month-to-month plans + mobile.
