Citing The Australian and the Australian Financial Review, Reuters reported that a team led by Australian cyber affairs ambassador Tobias Feakin visited New Delhi last week.

The AFR was quoted as saying: "Indian officials were keen to get an understanding of how the Turnbull government arrived at the decision to ban Huawei, and multiple discussions have been held over the matter."

It was claimed that Feakin explained "in detail" why so-called high-risk vendors had been banned from bidding for supplying equipment for 5G networks in Australia.

This is the second time that Australian officials have carried the US message to other countries, the first being when deputy head of the Office of National Intelligence, Andrew Shearer, travelled to the UK to try and influence that country's decision on the use of Huawei gear, according to a report in the Sydney Morning Herald.

Australia's high commissioner to the UK, George Brandis, has appeared before the Intelligence and Security Committee and suggested that it would be better for all the Five Eyes nations — the US, Canada, the UK, Australia and New Zealand — to adopt a united front.

The Australian said India had also spoken to the US about the ban imposed on Huawei in that country.

Contacted for comment, a Huawei spokesperson said the company had no response.

Apart from the US and Australia, New Zealand has not gone down the Huawei path either, but still claims that it has not banned the use of the company's gear.

Japan is the other nation that has said it will avoid using the Chinese firm's equipment.
