Amcon has signed a AU$12.9 million contract with SA Health to deliver data and network services across the state.
The contract between Amcon and SA Health is initially for three years, with a pair of three year options.
Amcon and Vocus Communications CEO James Spenceley said the deal reflects the company's ongoing efforts to build its relationship with the public sector.
"With a number of projects already on the go in both Western Australia and the Northern Territory, the new deal in South Australia, which spans all SA Health services across the state, will continue to build our experience and expertise in the government sector," he said.
The win comes off the back of Amcom's appointment as a key supplier to the South Australian government's network carriage service panel, a deal valued at AU$12.9 million over three years. In addition to this, Amcom has a long history with both the Western Australian and Northern Territory governments.
The remainder of Amcom Telecommunications was acquired by Vocus at the end of last year. Vocus also attained Federal Court approval in June to complete the acquisition after the latter's shareholders voted in favour of the AU$1.2 billion takeover, despite efforts by TPG to block the deal.
However, Vocus reported its financial results for the 2015 full year, the company noted it did not take into account the acquisition of Amcom in its results as the deal was finalised after the year ended.
In November, the Australian Competition and Consumer Commission (ACCC) gave the green light for the merger of Vocus and M2 Group, forming the fourth-largest telecommunications provider in Australia and the third-largest in New Zealand, worth more than AU$3 billion.
