PM rejects machismo response to IS

IN A major national security speech to Parliament on Tuesday, Malcolm Turnbull belittled IS and urged a calm and careful response to the Paris attacks.

The Prime Minister described IS as weak and said it had "many more smartphones than guns, many more Twitter accounts than soldiers".

He conceded a terrorist attack remained likely in Australia but said the November 13 attacks in Paris had not materially changed the threat on home soil and he had no plans to send ground troops to Syria.

"This is not a time for gestures or machismo," he said.

"We should grieve and we should be angry, but we must not let grief or anger cloud our judgment."

Mr Turnbull announced the government would this week move to a new terrorism alert system to provide the public with more information on the nature of terror threats.
