The hosts are very much the favourites in their semi-final against UAE, but Ali believes his side are willing and able to provide another upset like they did when they knocked defending champions Japan out of the tournament.
Ali said: "We are very well prepared for this game. We've planned to come to this level for a long time and we will work very hard to achieve our goal in the semi-final against Australia.
"Two years ago we announced that our goal was to reach the semi-finals and our goal has already been achieved, we are happy about that.
"Now we aim to reach the final. We have worked really hard to reach this level and we won't let it go very easily."
He added: "The Australian team is one of the best in Asia and we have seen that as they have qualified for the semi-finals.
"I think they are a good team, they have a good mixture of younger and experienced players.
"[It] will be a tough game for both teams and we will do our best to achieve our goal."
