The Socceroos can't afford to make any mistakes if Kuwait put 11 men behind the ball in their World Cup qualifier, midfielder Jackson Irvine says.
Australia begin their campaign for a berth in Qatar in three years time at the Al Kuwait Sports Club Stadium on Tuesday night (1:30am AEST on Wednesday).
The Socceroos easily beat Kuwait 4-0 in a friendly in October, but the Blues are brimming with confidence after throttling qualifying Group B minnows Nepal 7-0 on Thursday.
On paper the world's 156th-ranked side should be a walkover for Australia, but Irvine believes the hosts pose a threat even if they play more conservatively.
The Hull City midfielder says the Roos can't afford to be wasteful or complacent if Kuwait try to park the bus because any mistakes will be punished.
"Maybe the biggest danger is yourself, maybe mistakes and giving some time to these teams that like to sit a little deeper," Irvine said.
"We know we generally have more possession in the qualifying campaigns, so it's about being ruthless in front of goal and ruthless in both boxes, and not letting them get something to hold onto.
"We just have to just focus on our own game plan, both defensively and in an attacking sense. If we can do that we know we can cause any team problems."
With the temperature set be between 37-41C during Tuesday night's match, the Socceroos have been training in Dubai for a week to try to acclimatise.
Irvine says many Australia stars play their club football in more temperate Northern Hemisphere climes, so the desert heat can be punishing.
"Speaking to the boys we were talking about playing in the UAE in the last campaign, in Saudi Arabia and playing high 30s lows 40s temperatures, it is something totally different for us playing in the UK or Europe, but you just have to adapt and do as best we can," he said.
"The conditions will always play a part that's for sure. You just have to deal with it and try not to use it as an excuse. It's just a fact of playing in Asia."
