The German-born coach had just seen his side move up to second in Asian qualifying Group B when he quipped "women should shut up in public" to journalists.
Osieck was taking his seat at a press conference following the game when he jokingly accused a female Football Australia official of ordering him around.
Osieck then said something in German, before translating it as "women should shut up in public. I say it to my wife at home, it is a private one, OK."
He added: "And you record that one as well? I am going to be the darling of all Australian wives."
On Wednesday Osieck tried to downplay the remarks, claiming they had been made off the record.
He told a media conference: "I got information it created waves. That was not the intent. To everyone offended, I sincerely apologise.
"It was off the record and ... a complete misunderstanding. It was more meant as a joke. There was no seriousness in it.
"If my wife knows I'll probably be in big trouble when I get home."
