A teenage boy in Sydney could face 15 years behind bars after being charged with several terrorism offences.
Police will allege the boy, aged 16, held a "mixed ideology plan" and had plans to carry out acts of violence after analysing extremist material found on a computer he allegedly owned.
Investigations into the boy began last year when police searched a home in the Inner West, where a gel blaster and a flick knife were found.

The boy was initially arrested and charged with possessing an unauthorised pistol and a prohibited weapon without a permit, and was granted bail for each offence.
However, after finding the alleged extremist material, authorities have laid further charges on the boy.
These include one count of collecting documents likely to facilitate a terrorist act, two counts of making documents likely to facilitate a terrorist act, and two counts of possessing violent extremist material.
The boy will face NSW Children's Court today.
