Hobart: Australian players tested a new helmet safety attachment -- designed in the aftermath of the Phillip Hughes tragedy -- on Thursday although they will not be obliged to wear it in matches, Cricket Australia said.

Steve Smith, Glenn Maxwell and George Bailey all wore the new Masuri StemGuard clip-on, made of honeycomb plastic and foam, while they batted in the nets at Bellerive Oval ahead of the World Cup match against Scotland on Saturday.
