A leading Islamic expert with Charles Sturt University (CSU) has commended Australian police and other security agencies on recent action to prevent what they considered an imminent terrorism risk.

Associate Professor Mehmet Ozalp said the raids demonstrated that existing terrorism laws in Australia were sufficient to protect the population.

"So the case to give further powers through new terrorism laws which could limit civil liberties collapses with these raids," Professor Ozalp said.

The Director of the University's Centre for Islamic Studies and Civilisation reminded the public that people should be presumed innocent until proven guilty in court.

"Public hysteria over these police raids and extending the accusations to the entire Muslim community runs the risk of not only violating this principle but it also indicates a related problem of 'Islamophobia' in our society," Professor Ozalp said.

"I believe radicalisation and Islamophobia are closely related and feed from one another to perpetuate their rhetoric and maintain the recruiting power of extremists."Unless we see the issue as a whole and deal with both issues together we will not be able to contain and get rid of them. We run the risk of tearing the very fabric of our society."
