Shadow Communications Minister Malcolm Turnbull has pledged to revisit the prohibition imposed by the Labor-led government on giant Chinese network specialist Huawei Technologies.

"We will review that decision in the light of all the advice in the event of us coming to government," Fairfax reported Mr Turnbull as saying on Tuesday.

Earlier this year, Huawei was excluded from participating in any tender involving the $36 billon roll out of the national broadband network, with strong recommendations from Attorney-General Nicola Roxon that allowing the Chinese firm some in roads into the project could pose national security problems for Canberra.

Prime Minister Julia Gillard has constantly defended her government's decision on the matter, insisting that it was in line with national interest, which she added was foremost importance to any nation, China including.

Ms Gillard said she was firmly convinced Beijing would fully understand Australia's position.

Huawei, however, has reiterated this week that locking the firm out of the NBN project was counterproductive both for Australia and the telecommunications company, which is now regarded as the second biggest on its field and not too far from Europe's Sony Ericsson.

In its submission before a Parliamentary inquiry, Huawei bemoaned that it was singled out by the Gillard Government purely on the basis that it was a Chinese company and therefore an obvious security risk.

While it understands that Canberra must safeguard for Australia's security and adopt regulatory measures to support such aim, Huawei argued that it should been allowed to fully "understand and address specific concerns," on how it conducts business in any given country.

Instead, it was "being subjected to regulations based on rumours and accusations instead of objective evidence and legitimate security concerns," Huawei told the Parliament.

Huawei noted too that it has considerable presence in Malaysia, New Zealand, Singapore and even the United Kingdom with no problem at all with these nations' governments.

Mr Turnbull said he is aware of the fact that the British government has permitted Huawei to actively participate on its broadband project and "obviously they've (Britain) got very similar security concerns that we do."

The differing policies from two closely related nations were a puzzle to him, the former Coalition leader allowed.

But he quickly clarified that what he knows on the matter at the moment could be considered inadequate as to what the Labor government has.

"Having said that, we have not been privy to the security intelligence advice that the government has had," Mr Turnbull was reported by the Australian Financial Review (AFR) as saying.

He stressed nonetheless that "we need foreign investment, we should welcome it, and any suggestion that the Coalition does not do that is simply wrong."
