Lendlease has put the balance of its Bingara Gorge housing estate in Wilton in the Macarthur region south-west of Sydney up for sale in what is likely to be one of the biggest residential land offerings this year.

It comes to market after state-owned Chinese developer Poly’s sudden decision in September last year to abandon a $300 million acquisition of the estate and its 18-hole golf course following a directive from Beijing.
