Based on the provided comments, it appears that the caller with the number +61399614770 is likely a scammer trying to steal personal information or money. The presence of robocalls and recorded messages suggests an automated system is being used to make these calls. The fact that multiple users have reported receiving suspicious calls from this number and have flagged it as spam further supports this conclusion. The mentions of "Health connect survey" could be a tactic used by the scammers to appear legitimate.
The caller was unknown, no message was left, my phone flagged it as spam, and the starting digits are similiar to other robo-callers, thats suspicious.

Due to numerous suspicious calls from the 03 area code, it's now assumed that any call from this code is spam, and the call is not answered unless a message is left.
A survey related to health services was the purpose of the call.
I got a survey from health connect, it was pretty straighforward.
