De Silva learning from Jedinak, Cahill
De Silva, 18, could make his Australia debut when Ange Postecoglou's men take on Kyrgyzstan in a World Cup qualifier on June 16.
But the Roma-bound De Silva is getting plenty out of the camp in Dubai, especially from the likes of captain Jedinak and stalwart Cahill.
"Obviously everyone here is very professional, especially those players [Jedinak and Cahill]," he told FFA TV.
"So just being able to learn off them on and off the pitch will be such a great thing for me and help my professionalism to become better as well.
"They've played at the highest level so just watching them and watching what they do will definitely help my career."
De Silva is the youngest player in the squad and the only teenager – with Lazio's Chris Ikonomidis having turned 20 in May.
The former Perth Glory attacker is excited by a potential debut.
"I think I've always been the youngest probably anywhere I go," De Silva said.
"I'm just going to enjoy this experience and if I get a chance to play that'll be fantastic but obviously that's up to the boss and we'll see what happens.
"I'm just really happy to be a part of the squad and a part of what the plans are for the future."
