A Sydney man who produced a do-it-yourself terrorism book has been sentenced to at least nine years in jail.

Last year a Supreme Court jury found 39-year-old Belal Khazaal guilty of producing a book, knowing that it was connected with assisting a terrorist attack.

The court heard that he compiled historical and religious writings about how to shoot down planes, strike motorcades and assassinate high-ranking government officials in Australia, the United States and other countries.

The book was called 'Provisions on the Laws of Jihad,' it was written in Arabic and was posted on the internet.

Khazaal's lawyer argued that he did not check all the material he compiled from other writers.

But the judge said it 'beggars belief' that a person of average intelligence would not register the nature of the material.

Today in the Supreme Court, Khazaal was sentenced to 12 years in jail with a non parole period of nine years.

After he was sentenced, his supporters shouted abuse at the Bar table in Arabic.

Outside court, they said he has been unfairly treated because he is a Muslim.

Khazaal's lawyer says there will be an appeal.
