The Attorney-General's Department responded to the FOI request asking about evidence related to AI bots making FOI requests:

https://www.righttoknow.org.au/request/evidence_related_to_ai_bots_maki#incoming-43611

The released documents include some de-identified submissions they suspect of being AI generated.

Some of it just looks like sovcit copy paste nonsense. But it seems to mostly be individuals using tools rather than automated submission of requests.

@daedalus may be interested if he hasn't already seen it.
