'The WAYRBA was established in 1970 and is voted on by young readers across Western Australia.
'The Award operates on three levels, Younger Readers, Picture Books and Older Readers.
'Readers are invited to nominate, through their libraries, books that they have enjoyed. These nominations are then considered by the WAYRBA committee and the three lists are drawn up.'
