Posting for all the Aussies here, an initiative of the Australian Centre to counter Child Exploitation I did not know existed.
It's called Trace an object and it "encourages members of the community to identify objects from the background of child sexual abuse material. Images only contain the content to be identified and have been sanitised for public viewing."
Below it's a video that explains the initiative, the source link for this material and the direct link to the page with the pics (nothing visible other than normal everyday objects, but trigger warning anyway)
