Corporate advisory partner Adam Laura led the transaction and was assisted by senior lawyer Peter Reeves.

The Fund will be renamed the Australian Unity Diversified Property Fund and all existing unit holders (apart from WBC) will retain their investment in Fund.

"This is a great result and in line with WBC's strategic review of its property funds management business." Laura said.

Gilbert + Tobin also recently advised WBC on the merger, by way of trust scheme, of the Westpac Office Trust (WOT) with the Mirvac Property Trust.
