I've had missed calls from this number twice today - once in the morning and another in the afternoon. I don't answer calls from numbers I don't recognise, and they never left a voicemail or message either. Truecaller lists this number as "Health Check Spam". I see that on this site someone has mentioned it was AI asking about super, so I've just blocked it now.
I also had another missed call from a separate almost idential number but the last 3 digits were different 0489 935 315) 2 hours before the afternoon call. Again, I did not answer, and they left no message, but could not find any information about that other number online. Hope this is somewhat helpful.
