Somerset have signed Will Sutherland for the start of the new county season.
The 24-year-old Australian is available for the opening rounds of the County Championship and a "selection" of T20 Blast matches, according to the club.
Sutherland, the Victoria captain, who has 115 wickets and 948 runs in 37 first-class matches agreed to join Essex for the 2023 campaign before a stress fracture saw the deal cancelled.
"It's an exciting opportunity for me," he said. "Somerset are the 2023 Blast champions and have an excellent pedigree in County Championship cricket which shows the level of desire and ambition that the club have.
"That really resonates with the ambition that I have within the game. I'm really looking forward to contributing on the field, getting to know the players and staff and challenging myself in English conditions.

"I'm delighted to be gearing up for my first taste of county cricket with Somerset. I've spoken to Peter Siddle about the club and life in Taunton and he only had good things to say, so I can't wait to get started."
Director of cricket Andy Hurry added: "Everyone who follows global domestic cricket will be aware of the rise Will has made in recent seasons.
"He is certainly a talent across all the formats, and we sense he is closing in on full international honours.
"From the conversations that we've had with him in recent weeks, it's clear that he has a strong desire to constantly develop, push for higher honours and be part of a winning environment. This signing represents an opportunity for both Will and Somerset County Cricket Club to fulfil our ambitions."
