Vic Orthdox, aka Jack McNamara, just so happens to be away at the moment. Is this him playing for the Australia U-19s? He does fit the age.
And hes from Victoria, is this him playing in all of the Victorian teams on this next page.
I think it is, because I remember him mentioning a passing reference to being at those Australian U19 championships last year. Although I never suspected him there as a player.
