Asylum seekers being housed in the community, in places like university campuses, must respect Australian law, Tertiary Education Minister Chris Bowen says.
A Sri Lankan asylum seeker is due to face court in Sydney on Wednesday after being charged with the indecent assault of a 20-year-old student at Macquarie University on February 21.
Asked if campuses were appropriate places to house asylum seekers, Mr Bowen said the law should be allowed to take its course.
'Australian law applies to everybody, including those who are being housed in the community as asylum seekers,' the former immigration minister said.
'The law should be allowed to take its course.'
The 21-year-old Sri Lankan man was arrested on Tuesday.
An immigration department spokeswoman said on Tuesday the man was not living in student accommodation at the university.
Campus Living, part of Transfield Group, provides services for asylum seekers, including temporary accommodation, under a 2012 agreement with the Red Cross' Asylum Seeker Assistance Scheme (ASAS).
Opposition immigration spokesman Scott Morrison called on immigration minister Brendan O'Connor to review his department's system for releasing people into the community.
'Such a review needs to look at where the 10,000 people currently are across Australia that have been released into the community,' Mr Morrison told reporters in Melbourne.
He said the government had been asked last year if asylum seekers were being housed at Macquarie University.
'It's important that the government find out where these people are,' he said.
'They need to look at appropriate guidelines and what is an appropriate form of accommodation for people who are released into the community on bridging visas.'
