In an emotional press conference the Australian team captain Michael Clarke read a statement from the family of Phillip Hughes.
He said: "We're devastated by loss of our much-loved son and brother Phillip.
"It's been very a difficult few days and we appreciate all the support we have received from family, friends, players, Cricket Australia and the general public.
"Cricket was Phillip's life and we as family share that love of the game with him.
"We would like to thank all medical and nursing staff at St Vincent's Hospital and Cricket NSW medical staff for their great efforts with Phillip.
"We love you."
Twenty five year old Phillip Hughes made his Test debut in February 2009 as one of the youngest evers players to play his first match for his country.
In 26 Tests, he scored 1,535 runs with three centuries and seven fifties. He played his final Test at Lord's in London in July 2013.
