MEETING inside a garage in a quiet street in Regents Park over several months in 2014, at least six young men plotted to attack the Australian Federal Police (AFP) and Lithgow Jail to "achieve martyrdom".
Unaware that counter-terrorist investigators were monitoring the meetings in 22-year-old Sulayman Khalid's Berry Street garage which was known to the group as the 'wombat hole', they used code words to discuss their plans, which also included conducting "gorilla (sic) warfare)" in the Blue Mountains.
Last month, Mr Khalid who is also known as Abu Bakr, and two of his co-accused, 23-year-old Jibyrl Almaouie and a 16-year-old who cannot be identified, each pleaded guilty in the NSW Supreme Court last month, to conspiracy to commit acts in preparation for a terrorist act.
Two other men, Farhad Said, 25, and Mohamed Almaouie, 21, have previously admitted to possessing documents connected with the preparation of a terrorist act.
All five men will face a sentencing hearing on October 3.
A sixth man, 21-year-old Ibrahim Ghazzawy, was jailed for eight-and-a-half years to serve at least six years and four months.
A statement of facts tendered at Mr Ghazzawy's sentencing in May, noted that he adhered to the religious ideology Wahhabi-Salafism, which inspires Islamic State, or ISIS, Al-Qaeda and like-minded groups.
A series of documents found in Mr Khalid's garage during raids in December 2014, included one note which read: "If we are gonna do the Istishadi the AFP building is a good target, its in parra or the city.
"They will catch up with us anyway. Helicopters and all that so we are going to fight till shahada anyway so we might as well do something major."
According to the court, 'Istishadi' is the Arabic word for 'martyrdom', 'death of a martyr', or 'heroic death', while 'shahada' is the Islamic creed.
