Oxford Properties has reaped $1.1 billion so far in an extensive divestment of office towers from the holdings of the formerly listed Investa Office Fund after it was bought out by the Canadian giant last year.

The Canadians have just two properties left in play after earmarking a $1.8 billion group of assets to carve out and sell out of the Investa fund's $4.3 billion portfolio. Of the 10 towers to be sold, only the Piccadilly Complex – its joint owner is Stockland,which will be given a pre-emptive right to bid on it as well – in the Sydney CBD and 99 Walker Street in North Sydney are left. The fate of a third tower, 6 O'Connell Street, is under review.
