Preston North End delighted with capture of Aussie youth duo
Defender Wright, 17, hails from Melbourne and has represented Australia's U17 national team while midfielder Parrish comes from Sydney, having previously had trials with Bolton.
Preston academy boss Dean Ramsdale said: "Bailey is a centre-half who likes to head, kick and tackle, but the boy can also play.
"Cameron has all the tricks and is technically very very good with two good feet.
"They're complete opposites as footballers but we feel they'll complement our youth team well."
