Immigration Minister David Coleman has told reporters that proposed legislative changes would 'further strengthen' provisions under the Migration Act and allow decision-makers to take a stronger stance on offenders. A total of 4,150 visas of non-citizens who committed serious crimes in Australia have had their visas cancelled in the past five years. Image: News Corp Australia
