Australian Rugby Union boss John O'Neill says he expects the Super rugby competition to expand to 15 teams in 2011.
O'Neill says talks have recommenced between the SANZAR working party after a breakdown in discussions late last year over a proposed six-team finals series.
The ARU chief indicated that a Super 15 competition running from March to August in 2011 would involve an extra team from either Japan or the Pacific Islands and would incorporate six teams in the finals.
In the proposed expanded format, teams would play each other once in a round-robin competition before teams from Australia, New Zealand and South Africa would play teams from their own country again.
O'Neill says under their existing broadcast deal they have to have a proposal to their broadcasters by the 30th of June this year.
Any changes to the competition have to be unanimously agreed to be the SANZAR partners.
