Here are the rules as outlined in the NSW Police Force Media Handbook
Members of the public have the right to take photographs or film police officers which are observable from a public space or from a privately owned place with the consent of the owner or occupier.
Generally speaking, if a person takes photographs or videos Police Officers, operations or incidents from a public space, Police do not have the power to:
prevent the person from taking photographs or filming
confiscate photographic or filming equipment
delete images or recordings, or
request or order a person to delete images or recordings.
If Police Officers try to confiscate equipment or interfere with members of the public to delete images or recordings, the officers may be liable for prosecution for assault or trespass to the person concerned.
