The Socceroos will look to maintain their winning streak in Asian World Cup qualifying against the 107th-ranked Omanis but Neill is aware it will not be an easy task.
"We know they're very difficult, we know they can cause problems because of the pace that they have. With their speed they can break on the counter," he said.
"We have to be playing to our potential, or as close to our potential as possible on the night, otherwise we could find ourselves in an embarrassing situation.
"Are we ready? Of course we're ready this is the reason we have come back to play this game.
"We had a good hit out on Friday night (5-0 win over Malaysia). Everybody has confidence, everybody wants to play and we have goal that is to qualify out of this group which means we have to win games."
Australia sits on top of the Group D table with two wins from two matches whilst Oman are on the bottom with one point courtesy of a scoreless draw with Saudi Arabia.
