Over 16 years, Goulburn's high-security Supermax facility has housed some of Australia's most notorious criminals, including serial killer Ivan Milat.
Now, the New South Wales government says the jail will be upgraded to include a specialised unit to house up to 54 convicted terrorists.
Specially trained corrective officers are also being introduced to work on new de-radicalisation programs.
The upgrades will cost 47 million dollars over three years, and the government hopes to have it completed by the end of 2018.
Premier Gladys Berejiklian says with recent terror attacks around the world, nothing can be left to chance.
