The 31-year-old agreed a two-year deal with Glory, which will see him return west after stints with Melbourne Knights in the VPL and Newcastle.
''I wanted to stay in Newcastle. That was my first choice,’’ Young told the Newcastle Herald.
''It wasn’t an easy decision. I dwelled over it for two weeks.
''Financially the Jets offer wasn’t as good as Perth.
''I would have taken less money to stay in Newcastle if it was for two years, but they weren’t able to do that.
''I have to look after my family’s future.
''Perth have given me two years, which is my future, and will also help me with life after football by putting me through [goalkeeper] coaches courses.’’
Young will link up with Perth as understudy to Danny Vukovic with the Jets likely to offer Matthew Nash a deal to act at first-choice Ben Kennedy's deputy.
