Convicted terrorists will soon be banned from speaking and writing letters in Arabic during visits and phone calls at one of Australia 's highest-security prisons . Under tough new restrictions , 13 prisoners , who are classified as 'Extreme High Risk Restricted' at SuperMax , the compound located within Goulburn jail in NSW , will only be allowed to speak English . State Attorney General Brad Hazzard has called on the laws to take place in a bid to stop radicalisation of Muslim inmates from converting other prisoners , The Sunday Telegraph reports . The law pledges to have prison officers strictly monitor conversations between inmates and visitors as well as refuse or terminate visits if Arabic or any other languages are used . Convicted terrorists will soon be banned from speaking Arabic during visits and phone calls at SuperMax . It comes after the Australian Federal Police revealed the terror alert for police had been raised to 'high ' in the wake of terror plotting attacks and anti-terrorism raids across the country . Last September , it was revealed that inmates were able to plot acts of terror from behind bars because they were allowed to write letters , make phone calls and have visits . 'One of the issues that came out of that process was that some of these people , these high-risk ­inmates , were conducting their ­discussions in Arabic , or at least not English , ' Mr Hazzard said . But in rare cases , Mr Hazzard said inmates will be allowed to speak another language when their 90-year-old grandmother visits for instance but an immediate translator must be supplied . 'We do n't want to create a situation where they feel there 's no sense of humanity , because there will be , ' Mr Hazzard said . 'But they have to understand the people they 're visiting have put our community at risk . There has to be some clear boundaries and rules . ' Pictured left to right : Mohammad Kiad , Omar Al-Kutoki and Bassam Hamzy who will face the language ban . Omarjan Azari was arrested at his Sydney home in mid-September during the biggest counter-terrorism operation in Australia 's history . Among the 13 prisoners facing the ban will include Omarjan Azari , 22 who allegedly planned a plot to kill a random member of the public in the streets of Sydney . Mohammad Kiad , 25 , and Omar al-Kutobi , 24 , are also behind bars at SuperMaz after they were both charged with terrorism offences . The initiative was prompted when prison officers started noticing a rise of inmates converting to Islam , after switching their diet preferences from Western meals to halal , Sunday Telegraph reports . Meanwhile , four 'young , white males ' have lodged an application to have their diets changed at the Long Bay Correctional Complex at Malabar in Sydney on Monday . The law pledges to have prison officers monitor conversations strictly between inmates and visitors . Last September , it was revealed that inmates were able to plot acts of terror from behind bars because they were allowed to write letters , make phone calls and have visits . It 's reported that Bassam Hamzy , who was sentenced to life in jail for a 2002 murder and ran the 'Brothers 4 Life ' gang , is the first to be banned from speaking Arabic . The strict laws follows as prison authorities have banned Islamic prayer meetings in some of Sydney 's jails after intelligence found some key jihadist figures were operating from behind bars . But Mr Hazzard added that he has called on the department to recruit imams to lead prayer sessions with 'moderation and decency ' as it reveals prayer sessions will now be held in English .
