In the absence of injured regular skipper Paddy McCarthy, Jedinak led Palace to a 1-0 extra-time victory over Watford in the Championship play-off final at Wembley Stadium on Monday.
 
While he could be forgiven for looking ahead to matches against the likes of Manchester United and Arsenal next season, the 28-year-old's focus remains firmly on Australia's last three World Cup qualifiers, starting with a daunting match away to Japan on Tuesday.
 
"It hasn't sunken in properly yet," Jedinak said.
 
"I've got my thoughts somewhere else, my focus on something else at the minute and I'll remain that way until I'm done with this job," he added, referring to the Socceroos' crucial games against Japan, Jordan and Iraq.
 
Australia are third in Group B of AFC qualifying, one point behind second-place Jordan, with only the top two teams in the pool guaranteed a spot at the World Cup finals in Brazil next year.
 
While the games at home to Jordan and Iraq are likely to determine Australia's fate, Jedinak knows the importance of a good performance against runaway leaders Japan in Saitama.
 
"We have to approach the game very positively," he said. "It's going to be difficult, we know that. We're under no illusions but in saying that, I think we're a good side.
 
"We didn't perform the best against Oman, but we've got three games left to (attain) our ultimate goal, which is the World Cup. It starts with Japan.
 
"If we can bring our A-game, I think we'll give ourselves every opportunity.
 
"I think you have to look forward to these sort of big games ... It's always an honour to play for your country and you want to try and achieve things with your nation and qualify for major tournaments. This is no different and all the boys will be thinking the same way to be honest."
 
While Jedinak is likely to start in midfield for the Socceroos, emerging star Tom Rogic is far less certain of a place in the first team.
 
The playmaker earned a move from Central Coast Mariners to Celtic in January, and has won favourable reviews during his appearances for the Scottish Premier League giants, but Australia coach Holger Osieck is yet to entrust the 20-year-old with a regular spot in the starting XI.
 
"Whatever role I'm asked to play I'll be happy with," Rogic said.
 
"It's good to be a part of the squad and I'm very happy to be here. I'll keep doing whatever I can on the training pitch and show the coaches what I can do.
 
"Where that takes me, we'll wait and see. I'm ready for it."
