SYDNEY, Sept 5 (Reuters) - Australian office landlord Investa Office Fund (IOF) said on Wednesday it is adjourning a planned shareholder meeting that was set to vote on a takeover by Blackstone Group BX.N while it mulls the attractiveness of a higher rival bid.

Canada's Oxford Properties Group lobbed a last-minute A$3.3 billion ($2.4 billion) offer on Tuesday, A$90 million higher than Blackstone's. Investa said in a statement the meeting, set for Thursday, would be adjourned so that offer could be considered.

Blackstone, in a letter to Investa that was seen by Reuters, said the Oxford offer was "not a superior proposal" and that it reserved its rights to terminate its bid and claim a break fee if the meeting were to be adjourned and Oxford's offer deemed better. ($1 = 1.3906 Australian dollars)
