So him playing an age group FIFA comp for Australia doesn't count?
(honest questions, I have never truly understood these eligibility rules)
His father is English, mother is Filipino, born in NZ and been in Aussie for 5+ years (he is only 20, so hasn't done the 5 yrs over the age on 18, so Aussie must have applied for an exception for him), so he retains the ability to play for England, Philippines, NZ and Australia.
