Australian Prime Minister Tony Abbott stressed the necessity of a tighter migrant control, after two terrorism suspects, charged with preparing an attack, were arrested on Tuesday.
Abbott said that those applying for a residence permit in the country should be carefully checked and called for enhanced border security.
The two men were reportedly arrested only a few hours before the planned to carry out a terrorist act.
The first major Islamic terror act took place in Australia in December, when a man of Iranian origin took hostage several people in a Sydney café. The attack claimed lives of three people, including the attacker, and caused uproar in the country.
