Herd also qualifies for Scotland, but insists he would be available for the World Cup qualifier with Oman if not for a foot injury.
“I am totally committed to hopefully one day playing for Australia,” he added. “Injuries haven’t helped me when I have been named in squads and I’ll be cheering the boys on against Oman in what is a very important game.
“Hopefully I will get my chance at some stage because it’s a huge ambition of mine to play for my country,” Herd said. “Luck has been against me a little bit and I’ve had to pull out of squads.”
