The midfield stalwart has battled a groin injury for months and has been sidelined from Australia's World Cup qualifying campaign since June.
Jedinak was came on for the last half-hour of Villa's 0-0 draw in the derby against Birmingham City, his first appearance since Sept. 12, and impressed coach Steve Bruce.
"Once Jedinak came in, it stopped them and they weren’t as physical," he told British media.
"I thought Jedinak coming on helped us enormously."
Australia coach Ange Postecoglou would hope for a similar impact from Jedinak in the two-leg playoff against Honduras and the 71-cap midfielder was named in his preliminary 30-man squad for the ties.
The Central Americans host the first leg in San Pedro Sula on Nov. 10, with the second in Sydney on Nov. 15. The aggregate winners seal a place in the World Cup finals in Russia.
Postecoglou is expected to name his final 23-man squad this week.
