The 31-year old English-born former Portsmouth centre-back has played three times for Australia - all in 2012 - and is looking to impress Socceroos boss Ange Postecoglou ahead of this year's FIFA tournament in Brazil.
"It was a very proud moment," Smith told au.fourfourtwo.com of his Socceroos caps.
"I'm very honoured to represent Australia and given the chance from Holger (Osieck). Like all players, I want more but that's something that, the decisions out of my hands.
"The only thing I can do is to do consistently well at Brisbane and in (former Roar coach) Ange's eyes that's what he focuses on."
There are gaps in the Socceroos central defensive position at present with Middlesbrough's Rhys Williams going down with an Achilles injury this week while Lucas Neill is still without a club but Smith knows he needs to find consistency if he wants to challenge for a role at the 2014 World Cup.
"I'm sure that in every single Australian football person's mind is that there's always the opportunity," he added. "But for me at the moment it's making sure that I'm performing well on a consistent basis.
"I think that's all I can really do, focus on what's going on at Brisbane and making sure I'm injury free and I'm playing and performing well."
