Anthony Albanese not taking terror threats seriously “shows weakness” on the Prime Minister, according to security expert Lincoln Parker.

Mr Parker’s remarks come after NSW Police undertook a sweeping counter-terrorism operation across Sydney.

Five of those arrested have been charged with terrorism and extremism offences.

Meanwhile, ASIO boss Mike Burgess said this week there’s a 50 per cent chance of a terrorist attack in the next year.

“It shows weakness on the part of Prime Minister Anthony Albanese when he’s not taking these threats seriously and, at the same time, we’re getting a rise in threat level,” Mr Parker told Sky News host Erin Molan.
