Founded by James Spenceley[1] as a wholesale, business, government and consumer telecommunications provider, Vocus owns and manages Australia's second largest intercapital fibre network.

This allows Vocus access to the National Broadband Network backhaul and infrastructure in Northern Australia serving the offshore gas projects.

[9] Vocus was acquired by Voyage Australia Pty Limited, a consortium of Macquarie Infrastructure and Real Assets (MIRA) and superannuation fund Aware Super, in 2021.

[12] Two years later, Spenceley became one of the youngest Australians in history to run a company worth more than $1 billion after Vocus merged with Perth-based Amcom.

[17] In April 2015, rival TPG Telecom increased its shareholder stake in Amcom to 18.6 per cent in an attempt to block the merger.

On 25 June 2021, Vocus was acquired by Voyage Australia Pty Limited, a consortium of Macquarie Infrastructure and Real Assets (MIRA) and superannuation fund Aware Super.

[27] The same year, it acquired FX Networks,[28] a New Zealand-based fibre provider which services many of New Zealand's major organisations including many government agencies, telco carriers, ISPs and enterprises.

[40] In April 2007 Amcom Telecommunications completed the A$6.25 million acquisition of People Telecom's Perth-based corporate services business.

[41] The acquired assets include a client base using fibre and DSL-based broadband services and a large data centre facility with some 600 square metres of space.
