The Philippines will not accept any refugees sent by Australia if they are expected to live in the Southeast Asian nation permanently, President Benigno Aquino said Tuesday.

Aquino said he was "seriously considering" an Australian government proposal to accept some refugees but only if they were to transit in the Philippines before moving to another country.

Dutch far-right politician Geert Wilders was Wednesday shouted down by protesters as he helped launch a new political party in Perth, the anti-Islam Australian Liberty Alliance.

The Dutch firebrand and euroskeptic, who was controversially granted a visa, said the new party was modeled on his own Freedom Party in opposing "the Islamisation process".

Australian Prime Minister Malcolm Turnbull faced a grilling about his country's harsh immigration policies Saturday while visiting New Zealand on his first overseas trip since seizing power.

Australian police revealed Thursday a 12-year-old is on the radar of counter-terrorism authorities as Prime Minister Malcolm Turnbull urged closer cooperation with Muslim leaders at national security talks to tackle the growing extremist threat.

Hungary's populist prime minister called Friday on the U.S., Australia, Israel and "rich Arab nations" to take in some of the migrants flowing into Europe, while likening the influx to an "army".

Australia has launched a new bid to be elected to the United Nations Security Council, with Foreign Minister Julie Bishop saying the nation hoped to maintain its focus on international security.

Toppled Australian leader Tony Abbott took potshots at the new government Tuesday, saying it offered no new policies and that the nation should stop swapping prime ministers "like changing clothes".

The number of Australians fighting for the Islamic State group in Syria and Iraq doubled in the past year but was not expected to continue to grow so rapidly, Foreign Minister Julie Bishop said.
