Called me - unknown number so I didn't answer. No message left. I noticed that the number combination also looked suspicious as I have had spam calls from similar paterned numbers

Same as the above. Not in my contacts so did not answer.

Caller: Smart Health Australia

Charity on behalf of Parkinson’s Australia.

this number continues to call my phone, does not leave a message.

Got a call from this number, did not respond

Suspicious, no message left. Will see if it calls again or if anyone else can contribute.
