The chief executive of wealth management tech company Netwealth, Matthew Heine, and his wife, Alexandra, have emerged as the buyers of the Toorak mansion recently sold by Melbourne restaurateurs and culinary power duo Andrew McConnell and Jo McGann.

The Struan Street property sold early last month for about $22 million, less than a week after it was listed by Marshall White’s Marcus Chiminello and Nicole French and after just one inspection. The property is yet to settle.
