Australian Prime Minister John Howard says his government has received information about a specific terror threat, but would give no further details about it.
Speaking to reporters at a morning news conference on Wednesday, Prime Minister Howard said the government received the information this week.
Mr. Howard said he would try to push new anti-terror legislation through parliament on Wednesday to help law enforcement agencies fight the threat.
New counter terrorism laws under consideration in Australia would allow suspects to be electronically watched or held in custody for up to 14 days without charge. They would also create tighter checks on citizenship applicants and authorize jail terms for inciting violence.
Rights organizations have criticized the measures, saying they threaten civil liberties and violate international law.
