The project, initially awarded to Chinese firm Huawei Telecommunications by the Solomons, was later awarded to Australian company Vocus Group after the intervention of the spy agency, the Australian Secret Intelligence Service.
The prime minister of the Solomons, Rick Houenipwela, is on a visit to Australia. He and Australian Prime Minister Malcolm Turnbull will sign an agreement in Canberra for the first stage of the project.
Australia confirmed in April that there would be no role for Huawei, when Turnbull said that Canberra would provide most of the funds, with a small co-contribution from PNG and the Solomons. The ABC's AM program said the cost to the Australian taxpayer would be in excess of $100 million and it would come from the aid budget.
In New Zealand last week, Houenipwela confirmed that Huawei had been forced out of the cable project due to Australia's security concerns; however, he did not elaborate on what those concerns were.
Last July, it was reported that Australia was putting pressure on the Solomon Islands to withdraw from the Project Honiara undersea cable project after the contract was awarded to Huawei.
Security concerns were said to be the reason why Australian officials had made the request which was, tellingly, conveyed to then Solomon Islands Prime Minister Manasseh Sogavare by Nick Warner, the director-general of the spy agency ASIS.
Officials of the Department of Foreign Affairs and Trade have said that Huawei did not approach the Australian Government to obtain leave to connect into the Australian network before the government made its offer to the Solomon Islands.
Daniel Sloper of DFAT's Pacific division, told a Senate Estimates hearing in May: "In terms of Huawei, the company you mentioned, at no point did that company or, in fact, the Solomon Islands' responsible telecommunication authority that would be submitting applications, put forward an application to Australia."
Comment has been sought from Huawei.
