And with less than five months to go before the Lions head to Oz via Hong Kong, Irvine is seeing first hand how quickly the excitement is building in the host nation.
"There is already a massive interest over here in Australia. The people we've met and spoken to are all licking their lips at the prospect of the Lions visiting here," said Irvine.
"We only come to Australia once every 12 years, and the Australian players have said that, other than the World Cup, this is the biggest event for them.
"I think it will be the biggest event in the sporting calendar in 2013. Australia is a fantastic country and the atmosphere out here will be just incredible.
"It's going to be some contest, there's no doubt about that. What we'd love to do is come back here and show our supporters that we're capable of winning a series. It's going to be a magnificent occasion."
