Developers of fast food outlets and childcare centres were the big winners at a sold-out commercial property auction in Sydney as cashed-up investors, seeking the safety of bricks-and-mortar assets on long leases, forked out almost $50 million in just a few hours of bidding.

Nearly 120 bids were received in total for six fast food outlets spread across the country – from Mt Gambier in SA to Caboolture in SE Queensland – that were offered as part of a Burgess Rawson portfolio auction.
