Beau Casson and Adam Voges made their debut for Western Australia on the same day in 2002.

For the past seven years, they have worked together as coach and assistant of the WA side, and bonded over tea and biscuits as roommates on away trips.

Now they will share the two most important jobs in WA cricket.

Casson was on Tuesday unveiled as his great mate’s successor in charge of the State’s one-day and four-day sides from next season, but Voges will retain the Perth Scorchers role.

He has signed a three-year deal.

“I think I am in a really good position to be able to take the group forward and also I am very, very hungry for this State to continue to have success,” Casson said.

“(Voges) is a tactical genius, there’s no doubt about that.

“We’ve known each other a long time, he’s a wonderful human being and I think we gel well.

“We have different views sometimes, but the great thing about it professionally is we are able to respect one another’s opinions and it’s always with the best interest of WA cricket at heart.

“No doubt moving forward that will continue.

“I really enjoy a cup of tea and a chocolate biscuit at night and I get to room with Adam Voges, so we always spend quite long hours at night talking about how we can move the program forward, how can we improve the players and our coaching staff.”

The former WA, New South Wales and one-Test spinner has served as his former side’s batting and spin coach since returning to the west from Sydney, where was an assistant at the NSW Blues and Thunder.

Casson, now 43, retired from cricket as a 28-year-old after battling a heart condition.

He says he always had an eye on coaching and considers his early exit from the game a leg-up in what has become one of Australia’s most promising coaching careers.

“I think I’m in a great position in terms of I’ve had a long coaching background. I finished playing early ... so since the age of 28 I have been in a high-performance setup,” he said.

“From the age of about 23, 24 I started to think along the lines of coaching, less about my game and more about other people.

“I begun that journey probably a little bit earlier than some.”

Casson put a stake in the ground speaking for the first time after his appointment, declaring WA — who are condemned to finish last on the Sheffield Shield table for the second year running — must get better at handling their home conditions at the WACA Ground.

The WACA has proven tricky for batters this season and the home side have won there just twice since the 2024 shield final.

“We have seen recently our home conditions, we probably haven’t been owning that as well as we would have liked,” Casson said.

“That’s certainly an area we would like to attack and look to get better at.

“We have seen some glimpses of young players playing well on the east coast, but we want to make the WACA our fortress.”

The appointment of a new coach is expected to ramp up the transition of WA’s ageing list.

Voges has broken up the State’s greatest-ever opening partnership in their past two matches, sliding Sam Whiteman down the order and promoting Sam Fanning to bat with Cam Bancroft.

It has raised questions over Whiteman’s future in the side, given he has signed on to play as an Englishman with Yorkshire this winter.

But Casson backed Whiteman to retain the leadership through an off-season review.

“I certainly will talk to him and I definitely think he has a role,” he said.

“He’s been showing some great form in one-day cricket. Yes, he would like some more runs in shield cricket.

“I’ve got no doubt it will turn and when it turns it will turn big.

“At this stage I don’t see that (the captaincy) changing. Clearly we have got to talk and review and see where things are at ... and ultimately Sam needs to be a big part of that as well.”

Voges will lead WA for one final time in the shield match with NSW which begins on Saturday.
