(Reuters) - Australia said on Sunday it is stopping  undesirables  such as terrorists, pedophiles, organized criminals and drug smugglers from boarding flights to the country, defending its hardline immigration policy that has drawn criticism from rights groups.  Immigration Minister Peter Dutton said that Australian Border Force Airline Liaison Officers were operating in major transit airports to push those threats  beyond our borders .  Where other countries  allow people to arrive and then assess the threat then , the  Australian model  was to bar those considered a threat.   (Liaison officers) try to identify the threats   particularly given that we ve got foreign fighters coming back through Southeast Asia and all over   the idea is to stop them getting on planes,  the minister told the Nine Network.  According to media, immigration officials prevented 1,043 passengers from boarding flights to Australia since 2013. Australia has seen the rise of nationalist, anti-immigration politics with far-right wing parties such as One Nation garnering strong public support, while the popularity of the ruling center-right government has been languishing. Under its policy on asylum seekers arriving by boat, Australia turns back unauthorized vessels at sea to their port of origin when it can and sends those it cannot to controversial camps in the South Pacific for long-term detention. Earlier this year, the government announced it would raise the bar for handing out citizenships by lengthening the waiting period, adding a new  Australian values  test and raising the standard for English language as part of a shake up of its immigration program.
