Graham Arnold's new-look Socceroos squad will face Lebanon in a friendly on November 20 at ANZ Stadium.
"It's still up to David and Timmy's management exactly what it is," Arnold said when asked if Cahill will play.
"It's a probably a wonderful opportunity for fans to thank Timmy for what he's done for Australian football. It's all about respect for Timmy.
"We'll do something that he nevers forgets."
After unveiling his first squad for a training camp in September, Arnold is excited at the prospect of back-to-back fixtures against Asian opposition in November ahead of the Asian Cup.
“The fixtures that have been scheduled in Brisbane and Sydney will provide us with valuable match minutes against strong Asian opponents, and this will only help us to improve as a team," Arnold said.
“The players are excited to return to Australia to play in front of their families, friends, and fans, so we look forward to playing in front of large vocal crowds at both matches.”
The Socceroos have only ever once played Lebanon with the green and gold claiming a 3-0 win when they met in September 2012.
FFA CEO David Gallop is excited to see Australia return to ANZ Stadium and is looking forward to strong support for both sides.
“Sydney is also home to over 165,000 people with Lebanese heritage," Gallop said.
"We look forward to the opportunity of engaging with the Australian-Lebanese community over the coming months leading up to the match, and expect to feel a real party atmosphere inside ANZ Stadium on game day as the Australian-Lebanese community comes together."
