Australia coach Ange Postecoglou has trimmed his squad back to the final 23 for the World Cup.

He announced on Tuesday that Mark Birighitti, Josh Kennedy, Tom Rogic and Luke Wilkshire would be dropping out of a group captained by Mile Jedinak.

Mark Bresciano, Tim Cahill and Mark Milligan have all been selected, meaning they become the first Australian players to go to three World Cups.

Seven of the players named are currently on the books of A-League clubs.

"Every step of the selection process has been difficult because the players have worked very hard since they came into camp, but we have had to weigh up form, fitness and squad balance in coming up with the 23 players who will represent Australia at the 2014 World Cup," Postecoglou said.

"We've selected a squad that can do Australia proud, and they will walk out onto the pitch for the World Cup in the green and gold shirt and display the characteristics that define our country.

"Our stated aim is to make our country proud, show the world what Australians are made of and test ourselves against the very best football players in the world, and this group of players is capable of doing that."

Australia are grouped with Chile, Holland and title-holders Spain.

Australia squad: Oliver Bozanic, Mark Bresciano, Tim Cahill, Jason Davidson, Ivan Franjic, Eugene Galekovic, Ben Halloran, James Holland, Mile Jedinak, Mitchell Langerak, Mathew Leckie, Massimo Luongo, Ryan McGowan, Matt McKay, Mark Milligan, Tommy Oar, Mat Ryan, Matthew Spiranovic, Adam Taggart, James Troisi, Dario Vidosic, Alex Wilkinson, Bailey Wright.
