Jack Walker, defence innovation adviser to Pyne, was in the group of men seen sporting Malaysian flag budgie smugglers after Australian Daniel Ricciardo took out the Malaysian Formula 1 Grand Prix in Sepang on Sunday.

A spokesperson for Pyne said the matter is being handled by the Australian High Commissioner.

“Until we have a clearer picture of the process at hand it would be unwise to comment further,” they told AAP on Tuesday.

Sepang police chief Abdul Aziz Ali said on Tuesday the men were allegedly intoxicated when the incident happened.

The group is now under investigation for public indecency and disrespecting the Malaysian flag.

Sepang International Circuit chief Datuk Razlan Razali told the New Straits Times the men deserve to be locked up, investigated and have action taken against them.

“This shows a huge lack of respect to us as Malaysians; this is stupid behaviour from foreigners who have no sense of cultural sensitivity and respect,” he said.

“It embarrasses their own country as well – it gives Australians a bad name.”

Australia’s Department of Foreign Affairs and Trade is providing consular assistance to the men.

Treasurer Scott Morrison said the arrests were a timely reminder for young people to know and respect the laws of the countries they visit.

“They’re on their grounds, so you’ve got to comply,” he told Ray Hadley on 2GB radio.
