Oliver Peterson: Australian correspondent with the latest updates on the Sydney church stabbing - Heather du Plessis-Allan Drive

The stabbing at a church in Sydney's west last night has been labelled a terrorist act.

New South Wales police have revealed a young person's been arrested after three people were stabbed at Wakeley's The Good Shepherd Church last night.

A graphic video of the attack shows a person lunging at the Bishop during a mass.

Australian correspondent Oliver Peterson says religious leaders across Australia have stood by the church as more updates come to light.
