Rugby Australia has rejected accusations of discrimination after the Wallaroos and Black Ferns were unable to warm-up on ANZ Stadium before their first double-header with the Wallabies and All Blacks in Sydney.

New Zealand Herald writer Gregor Paul has slammed it as a “PR disaster”, claiming it proved Australia was not fit to host the women's 2021 World Cup.

New Zealand is competing with Australia for hosting rights to the showpiece women's tournament.

“It would surely have to be advantage New Zealand, if not game, set and match on the World Cup hosting front,” Paul wrote on Wednesday.

But Rugby Australia insisted there was no such “snub”, despite the All Blacks and Wallabies being able to warm up on the playing field as normal before their subsequent Bledisloe Cup clash on Saturday.

A RA official said neither the Wallaroos or Black Ferns complained after being advised they needed to warm up elsewhere.

“All sporting teams intending to warm up prior to gates opening are offered the designated warm-up facility adjoining ANZ Stadium,” the official said in a statement to AAP.

“This was communicated to both teams well in advance of the match, and the Wallaroos and Black Ferns agreed to use this facility for warm up (including the new High Performance Centre directly next to ANZ Stadium).

“Gates opened at 4.45pm, 30 mins before both teams ran out onto the field. In the event you liked this article in addition to you would like to receive more details regarding click through the up coming document generously pay a visit to our webpage.

“Rugby Australia has received significant support for the double header and the feedback has been immensely positive from players, spectators and broadcasters.”

While both women's teams will be allowed to warm up on Eden Park before Saturday's return double header in Auckland, the Black Ferns have reportedly declined the opportunity anyway.
