message on incoming call says 'suspicious calling pattern'

I can't be sure, but I was getting calls from Mater Lotteries around the same time, so I think it may be them as well.

Comes up with warning - suspicious calling pattern

Received a missed call from the number. No message left. Phone shows 'suspicious calling pattern'.

Caller: 0480 089 967

This mobile phone number is from Mater Lotteries, which is part of the Mater Foundation, an organization that raises funds for Mater Private Hospitals.
