Eight Royal Australian Air Force F/A-18 Hornets will fly into Perth today to give more firepower to the massive security operation to protect the gathering of world leaders during next week's Commonwealth Heads of Government Meeting.
The fighter jets, from Williamtown in NSW, will be on standby at Pearce airbase throughout CHOGM, ready to respond should a threat appear in the skies over Perth.
More than 1000 Defence personnel will be on alert in Perth during the event.
Several army Black Hawk helicopters were moved to the State several weeks ago and the SAS have been practising counterterrorism exercises for months ready to deal with any situation.
The commander of the task force charged with providing security for CHOGM, Rear Admiral David Johnston, said the Australian Defence Force would also have surveillance aircraft available in Perth, as well as the Hornets.
He said the pilots of the Hornets would carry out training missions over Perth in coming days to ensure they were familiar with the city.
The pilots of the Black Hawks are also set to ramp up their practice runs over the city in coming days.
Along with the jets and troops, the Government will use special mobile phone jamming devices in some areas of Perth as convoys of diplomats move through the city.
The jammers are similar to gadgets used by troops in Afghanistan designed to frustrate efforts to detonate roadside bombs.
