Unice made the decision to stand down just 11 days out from the Brave's semi-final clash in Melbourne, where a win would secure a grand final spot the next day.

Brave director Warren Apps said that achieving a sense of normality was paramount with Unice taking time to deal with "a number of personal issues".

"He's got some issues that are well outside hockey within his personal life that he's been dealing with for the last five or six weeks," Apps said.

"In the end as the pressure towards finals built there was a sense from him as well as from others that those issues and challenges that he was dealing with in his own life were starting to become a bit of a distraction to the team."

Assistant coaches Dave Rogina and Art Bidlevskii will take the reins as the Brave gear up for their third straight finals campaign.

"It's not our intention to bring in another voice or disrupt anything further," Apps said.

"There's no real changes to the systems that we've been working through. That's what we said to the playing group... everyone's role remains the same.

"Aside from the obvious, it's business as usual."

The Brave have one regular season fixture remaining in Sydney on Saturday before next weekend's semi-final.
