For the record, Hager denies the accusation, saying the only filming they did of Australia during the four nations tournament in April was their matches.
"We were going to send Ian Hicks, our video guy who's an Aussie, over to say 'hi' and take a couple of pictures, but no," he joked.
Of more pressing concern to Hager was the fitness of his players, particularly captain Kayla Sharland, who has a leg niggle.
"Yesterday was the first time we had our 16 Olympic players fully fit and training since we picked the team. Touch wood, it looks like we've turned the corner."
The Black Sticks played a practice game overnight against Great Britain and will play Belgium later in the week in their final tune-up. There's not a lot riding on the results but they could serve as a confidence booster after they were hammered 5-1 by Germany recently.
"Yesterday I walked away from training feeling the best I've felt for a while with this group. It was one of our better sessions. The girls are now starting to relax a little bit more," said Hager.
The Black Sticks have spent months getting their bodies adjusted to the early morning starts - the opening whistle against Australia is at 8.30am local time - and using Westlake Girls' High School's blue pitch to acquaint themselves with the colour change.
"It's a bit glary when you first get on there with the yellow balls, but you adjust pretty quickly," Sharland said.
