Australia is preparing to contribute up to 10 military aircraft to the increasingly aggressive campaign against the Islamic State (IS) extremists in Syria and Iraq.
Prime Minister Tony Abbott said in a statement issued that Australia was responding to a formal request from the United States for specific contributions to the international coalition.
US president Barack Obama announced the more aggressive military campaign last week.
Scores of US air strikes have been launched at select targets in Iraq, and US planes and drones will be gathering intelligence on targets before launching air strikes in Syria.
Australia will prepare up to eight F/A18 combat aircraft, an E-7A Wedgetail Early Warning and Control aircraft and a KC-30A Tanker and Transport aircraft to be deployed to the United Arab Emirates.
It said special operations personnel who could assist Iraq's security forces were being prepared also, but combat troops were not being deployed.
Politicians and the media should stop referring to the extremist group controlling parts of Syria and Iraq as "Islamic State" in a bid to discourage Britons from joining them, leading Muslims have warned.
The rise of the Islamic State of Iraq and the Levant (Isis) has been aided by the continuing failure of the US Government to investigate the role of Saudi Arabia in the 9/11 attacks and its support of jihadi movements such as al-Qaeda in the years since, says former Senator Bob Graham, the co-chairman of the official inquiry into 9/11.
