Australian Unity Office Fund's responsible entity said Starwood Capital Group, through Starwood Capital Asia Ltd., has been granted due diligence access for a four-week period following a sweetened A$2.95-per-unit buyout offer for the office real estate investment trust.

Starwood's increased bid follows its previous unsolicited, indicative and nonbinding proposals to the trust of A$2.56 per unit in May and A$2.72 per unit in July.
