B&I Lions name squad
The British and Irish Lions have announced their 37-man squad to face the Wallabies, with Sam Warburton the captain.
Cardiff Blues flanker Warburton was confirmed skipper at Tuesday's press conference, which saw fifteen Welshman included in the squad.
Surprising omissions from the group were Ireland hooker Rory Best, England flank Chris Robshaw and Scotland back-row forward Kelly Brown.
Not included in the squad is Jonny Wilkinson, with Head Coach Gatland opting for two fly-halves in the shape of Jonathan Sexton and Owen Farrell.
The Lions will take three scrum-halves on tour as Conor Murray, Ben Youngs and Mike Phillips have been chosen so Danny Care misses the trip.
The squad for the 10-match, three-Test series sees 10 Englishmen, nine Irishmen and three Scots join the 15 Welsh going Down Under.
"The announcement of a British and Irish Lions party is always a much anticipated and exciting event," said Irvine at the announcement.
"Selection for The Lions is the ultimate accolade and it is a great honour for all the players - they should be congratulated along with their clubs, provinces, regions and unions.
"We are fortunate to select from the very best of four nations and there will be some quality players who have sadly not made selection and will rightly feel disappointed."
Gatland added: "We spent a long time selecting this squad and there were some close calls with a lot of competition for places. But ultimately we chose the players who will give us the best chance of a Test series victory.
"A Lions Tour to Australia only comes around once every 12 years and we believe we have the right balance in the squad to be successful.
"We have a tremendous challenge in front of us but I know the players will be dedicated to the adventure and task ahead."
