I called back the number 0488 813 043 and reached vm that said I called an "outbound only phone number"

This male voice tried to get some superannuation infomation out of me.

Caller: Claiming to offer information about SuperInsurance

This sounded like a total scam call and I didn't let her finish, she started with "The Australian Government announced... superannuation insurance..." I figured mygov would give me the info I need on that, or my Super company would call me direct.
I didn't let her finish, told her I wasn't concerned about it, suspected she was a scammer and hung up. She sounded like she was calling from a call center.

telstra has this number listed as a potential fraud...
