Just thought of Rafael Rech, Liam Chipperfield and Giogios Okkas and why there hasn't been a bigger push from the media or this forum to get them into the Australian national team fold (whether under 20s, Olyroos or national team)  

Others i can think of.. 

Peter Gwargis
Noa Skoko 
Mo Toure (yes been capped once but not locked in) 


Any others?
