NSW teen to face terror retrial

A Sydney teenager accused of planning a terrorist attack will face a retrial after a jury was unable to reach a verdict.

His co-accused was found guilty by the NSW Supreme Court jury on Monday and a sentence hearing date is expected to be set on September 13.

Both teenagers, who cannot be named for legal reasons, pleaded not guilty to doing an act or acts between October 6 and October 12 in 2016 in preparation for a terrorist act.

The school friends were both 16 when they were arrested at a Muslim prayer hall in Bankstown in October 2016.

The Crown alleged they were in joint possession of two M9 bayonets and a sharpener bought for $230 at a nearby gun shop.

The jurors were discharged on Wednesday after they were unable to reach a verdict for the second teenager.
