Warren Gatland says Wales are "in a good place" as they prepare to launch their Rugby World Cup challenge against Fiji in a key match in Australia's group.
Gatland has been boosted by the return to fitness of 100-cap No.8 Taulupe Faletau, who will make his first Wales appearance since last season's Six Nations after recovering from a calf muscle problem that sidelined him for their three warm-up Tests.
He goes straight into the starting line-up, packing down alongside back-row colleagues Aaron Wainwright and skipper Jac Morgan.
"We've had some good clarity about what we want to achieve and the way we want to play on the weekend," Gatland said.
"The boys are looking sharp, there is a great environment in this group - players working for each other, enjoying each other's company.
"We are in a good place and can't wait to get out there and get our Rugby World Cup campaign under way."
Sunday's (Monday AEST) encounter in Bordeaux is huge in the context of a group where Australia and ever-improving Georgia will also be vying for qualification.
Gatland will become the first head coach to take charge of a match at five Rugby World Cups — four with Wales and one with Ireland in 1999.
There are five World Cup debutants in his starting line-up and it will be the fifth successive tournament where Wales and Fiji meet, with centre George North joining a select group of Welsh players to feature in four editions, emulating Alun Wyn Jones, Stephen Jones and Gethin Jenkins.
Scarlets halfback Gareth Davies has won the race for the number nine shirt.
"Twelve months ago I probably wouldn't have thought I would be involved in the first game of a World Cup, but anything can happen in rugby," Davies said.
"I have worked extremely hard over the last year to work myself into contention, and hopefully I can show that on Sunday.
"Playing in a World Cup is the pinnacle. We have a few young guys in the squad - they are really excited about it - and plenty of experience.
"Fiji are going to be a very tough team to beat, but it is a challenge we are looking forward to."
