Rocchiccioli comes to Edgbaston on the back of an outstanding Sheffield Season with Western Australia, which included career-best figures of 7/52 in February's match vs Queensland.
In an eventful and successful 24/25 season for Rocchiccioli, he represented the Renegades in the Big Bash, as well as taking four wickets in the match for a Cricket Australia XI vs England Lions.
Corey made his First-Class debut for Western Australia back in 2021 and has been a regular starter ever since across formats, building an impressive reputation with the Australian selectors.
The Bears will play four matches with the Kookaburra ball, taking on Somerset at Edgbaston starting next Sunday, 22nd June, followed by a visit to Hove and Sussex before the remaining Vitality Blast games play out. In July, Warwickshire will then play Worcestershire at home, followed be a trip to Chelmsford and Essex, before the Metro Bank One Day Cup and Hundred period.
Rocchiccioli said, "I’m really excited to play at a prestigious club like Warwickshire. I jumped at the chance to play when Westy (Ian Westwood) and Davo (Alex Davies) rang me.
"I’m really excited to learn and grow in English conditions and hopefully contribute to some strong wins along the way."
