Very well spoken Australian (older?) man. I don't remember his, or the company, name...
Asked if we were home owners under 60 and if so, there's a government incentive to use tax deductions to pay off our home loan.

I got rid of him easily enough. Redialed his number and got a recorded message saying something like "thanks for calling but all our staff are currently on other calls. We will return your call shortly". Call disconnected....

I called back number (02) 8325 1358 reached voice mail but did not say for what company.
