“It was entirely my decision, I didn't discuss it with Warren [Gatland], and it was the hardest thing I have had to do as a coach”
Robert HowleyWales caretaker coach
"James [Hook] is adept at playing at 12 and 10 and is a hugely talented player. His kicking was exceptional and his composure was fantastic under pressure [against the Barbarians]."
Wales' 16 frontline players flew out to Australia earlier this week before the Barbarians game, with defence coach Shaun Edwards, to prepare for the first Test against the Wallabies in Brisbane on 9 June.
Howley was left with 23 players to choose from for the clash with the Barbarians and has cut five players from the squad left behind.
He was quick to highlight the contribution of Cardiff Blues flyer Robinson who crossed for his first Test try for Wales.
Robinson scores brilliant debut try
"Harry Robinson was outstanding on the wing when he had time and space," said Howley.
"It was a Test match and we played like it. It was a huge squad effort this week. It wasn't pretty, there was a lot of turnover ball, but there's a lot we can work on in Australia.
"We're looking forward to it, it will be a momentous occasion next Saturday and we'll be going out there with every effort."
Ospreys fly-half Biggar, who left the field midway through the second-half with a shoulder injury, may have been doubtful for the tour but he wasn't selected for the final squad.
Flanker Williams, along with wing Shane Williams, played his last game of rugby at the Millennium Stadium and wasn't expected to make the trip Down Under.
Scarlets centre Warren, who made his Wales debut as a replacement against the Baabaas, Dragons wing Harries and Ospreys prop Bevington were all cut from the squad.
Ian Evans and Alun Wyn Jones will both miss selection for the first Test against Australia. Evans will miss the first Test in Australia to get married, while Jones could also miss out in order to attend his sister's wedding.
Ospreys provide half the pack, with Ian Evans and Alun Wyn Jones in tandem in the second row. Evans will miss the first Test in Australia to get married, while Jones could also miss out in order to attend his sister's wedding.
