Marsh, 25, has represented his country in all three formats, while remaining a vital player in both the Alcohol.Think Again Western Warriors and the Perth Scorches since his First Class debut in 2009. His breakthrough Sheffield Shield century came in the 2010-11 season and he went on to take 17 wickets the following summer.

Marsh’s leadership skills were identified early on, as he was named Captain of the Australia Under-19s for the 2010 World Cup in New Zealand and subsequently led the team to victory.

Marsh said he was honoured to receive the opportunity to lead his state and was grateful to have Turner named as Vice-Captain.

“I’m very proud to be named Captain; there are some great past players that have lead Western Australia and I’m honoured to be part of that,” Marsh said.

“We have a unique group, although it’s quite a young group, we have 22 guys that have great leadership qualities and we’re all one big leadership group. That’s also why I feel proud to be named captain because there were so many great candidates.

“Ashton is a really smart guy, really switched on with cricket and really respected within the group, so it’s great to have him to assist.”

Turner, 24, will head into his sixth season with WA after a breakout 2016-17 in which he scored his maiden First Class century with 110 against Tasmania, before following the milestone two matches later with 100 against Queensland.

Head Coach Justin Langer announced the appointments to the squad earlier in the week and said it was a difficult decision.

“The most pleasing thing for us is that this was a really tough decision. It’s been a really stringent process that has been going on for three months. The reason for that is because we had five or six guys that could have been Captain,” Langer said.

“This is such an exciting stage of Western Australian cricket with two young guys leading the team. When we started out five years ago one of our objectives was to develop these guys to become great players, great leaders and great people.

“Guys like Mitch, with so much international experience at such a young age will be so beneficial to have leading the group. AT has had recent success too which is such a good sign of what’s to come from both of these amazing players.

“It’s a really positive thing to have so many natural leaders in our group. The opportunity has gone to two fantastic young guys, knowing that they will have the support senior players like Michael Klinger and Shaun Marsh.”

WACA CEO Ms Christina Matthews said the appointments were a great opportunity for both Marsh and Turner, as well as an endorsement of the men’s program.

“This is such a great opportunity for Mitch and Ashton, two young men who have been in the system for a few years now get a chance to really step up and lead the group,” Ms Matthews said.

“It’s a credit to JL and the High Performance team that we have so many players that could have taken on this role, it’s a great sign of what’s to come for Western Australian cricket.”
