Australian Rugby Union CEO John O'Neill described as "nonsensical" the claim by International Rugby Board chief executive Mike Miller that New Zealand could be replaced at the next World Cup.
O'Neill said concern over the financial model under which the World Cup operates had unified the southern hemisphere rugby conglomerate SANZAR. But he expressed concern the debate over the Cup's future is being turned into a conflict between northern and southern hemisphere and that the real issues are not being addressed.
Australia is supporting New Zealand in its threat to boycott the 2015 World Cup unless concerns over the tournament's commercial procedures are addressed.
"Threatening to boycott a World Cup is not our style, but equally the notion that any team is replaceable is nonsensical," O'Neill told a news conference on Friday. "A World Cup without the All Blacks, the Wallabies or Springboks, I'm not sure you would be calling it a World Cup."
O'Neill said New Zealand and Australia's concerns were not being raised frivolously but represented very real worries about their financial future. Both Australia and New Zealand claim to lose money in Rugby World Cup years because of a reduction in the number of tests and restrictions on the activities of their sponsors.
