AC/DC producer and The Easybeats' star George Young has died at the age of 70.

AC/DC said in a statement the band would not exist without Young's "help and guidance".

"As a musician, songwriter, producer, advisor and much, much more, you could not ask for a more dedicated and professional man," the statement read.

"You could not ask for a finer brother. We will always remember him with gratitude and hold him close to our hearts."
