Operation Pendennis was Australia’s biggest terrorism investigation, which identified two extremist terror cells in Sydney and Melbourne in 2005.
Twelve people were arrested in Victoria and nine in NSW on November 8, 2005. Both cells were linked by radical cleric Abdul Nacer Benbrika.
The jihadi cells had stockpiled guns, explosives and bomb-making materials capable of carrying out a mass casualty attack.
The Sydney cell used false names to buy chemicals, including acetone and hydrochloric acid, and purchased PVC piping from different companies in 2005.
Some members went on shooting trips in remote NSW properties and travelled under false names. Thousands of rounds of ammunition, guns, extremist material and explosives were found after their arrests.
One of the plotters, Khaled Sharrouf, was sentenced to five years in jail. Shortly after his release in 2011 he travelled to the Middle East to fight for Islamic State. Authorities believe he was killed in an air strike.
