I also received 2 calls, 1 today and another on the 12th August 2019 that did not leave a message and when I called, I also reached vm advising all operators were busy and did not give company name! Number look up results showed Bribie Island or Brisbane as possible location. I have now blocked this number!

Caller: Scammer / Call Centre

They were asking about qualifying for government incentives (scam)

I called back the number (07) 3493 5981 and reached vm that did not mention the company name
