Anyone know what’s going on there?

Continuous AM transmission, loud in VK3, quite broad. Heard afternoons the last couple of weekends, and now today. 

Runs for hours on end, no break in transmission.

Initially I thought it was an open mike, hearing a bunch of people talking and rambling on not radio related, and then at times there seems to be playing of tape recordings of same. 

Doesn’t seem to be live conversations, because occasionally a local time is mentioned which is around midnight or early morning.
