Millward will go into camp with the Australian squad in Sydney on May 28 for the first time since January to prepare for the tri-nations which will be her first time playing in the run-on squad for her country.

She was selected in the top 15 players earlier this year after making the fringe squad last year, but also while recovering from a broken collar bone which has limited her contact training ability until this week when she hoped to be tackling again.

The tri-nations will be used as a stepping stone for the women's World Cup in Paris in October, and Millward is very keen to keep her spot in the side for then.

"The selectors have shown a lot of faith in selecting me with a broken collarbone and I want to reward that with a good performance in New Zealand for them, and not only myself," she said.

"I would love nothing more than to play at the World Cup. That would nothing more than a dream come true for me."

Although New Zealand will be used largely to prepare for Paris, Millward said Australia would still be taking their trans-Tasman rivals and Canada seriously.

"They will have had better preparation than us having played against some of the strong European sides, so we definitely can't take New Zealand and Canada lightly," she said.

"We need to put the impression in the minds of other nations that we will be competitive in this World Cup."

To date Millward has been training at home, training with the Whites women while working on fitness and building contact work.

She said she was looking forward to her first ever trip to New Zealand and experiencing their culture as well.
