Jorge Luis Pinto has accused someone in the Honduras camp of giving information to the Socceroos ahead of their World Cup play-off.
Honduras arrived in Sydney on Monday morning ahead of the second leg against Australia on Wednesday.
The first leg in San Pedro Sula ended 0-0, with Australia dominating the majority of the contest.
However, Pinto believes someone in his camp - staff or even the press - has been passing on information to Ange Postecoglou and Co.
Pinto told Televicentro on Monday: "[Australia] knew everything we were doing."
The Honduran media took it as a claim that someone close to the national team had passed off vital information to the Australians.
However, Pinto is still confident the side will make it to Russia 2018.
"They are the ones that are now under pressure," the Colombian said.
"In San Pedro Sula we were under pressure, but now it's them.
"That will suit us because it will leave us with a lot of space on the field.
"I plead with the people that they keep trusting us, because we are so close to reaching the World Cup."
