Border Protection minister said he was unable to comment when asked if Australian intelligence was tipped off by authorities overseas before they arrested four men in Sydney on Saturday.
It is alleged the four men planned to create a homemade bomb using wood scrapings and explosive material inside a piece of kitchen equipment.
Police seized part of a domestic grinder and a box containing a multi-mincer for making sausages from one of the men’s homes.
The plot may have involved sneaking the device in their hand luggage onto a flight from Sydney to the Middle East.
“There will be lots of speculation around about what the intent was, but obviously all of us have been working hard over recent days and we rely upon the expertise of the Federal Police and ASIO and other agencies,” Mr Dutton said.
“That’s the work they are doing at the moment. There is a lot of speculation around and I don’t want to add to that.”
“I can’t comment on that, because there’s information that I’ve received that is not publicly available yet, and I think it is an issue for the police to talk about,”
