Captain Travis Head has signed with Division One club Worcestershire after a brief spell with Yorkshire in 2016 under then coach Jason Gillespie.
The 24-year-old left-hander crunched 277 runs from just four List A matches and notched a first-class half-century in his last county campaign two years ago.
Head could be required for national duties in several limited overs matches against England in mid-June which may see him miss a few county clashes.
Gillespie will take the reins of Sussex in Division Two this year.
The Adelaide Strikers’ Championship coach will be hoping to recreate the success he had with Yorkshire after guiding the Vikings to back-to-back Division One titles in 2014 and 2015.

Gillespie will reunite with star Strikers spinner Rashid Khan in the T20 Blast competition.
Rashid will play the first seven matches of the series following his IPL commitments with Sunrisers Hyderabad as the talented teen continues to shine in short-form tournaments across the globe.
South African big-hitter Colin Ingram will look to lead from the front as Glamorgan’s new limited overs captain.
Ingram, who filled in as interim Strikers skipper on several occasions last summer, struck two centuries in last year’s T20 Blast series and was named T20 Player of the Tournament in 2016.
Fearsome quick Billy Stanlake has signed on for Yorkshire’s T20 campaign, while Peter Siddle is available for the opening five first-class matches with reigning champions Essex after previous stints with Lancashire and Nottinghamshire.
Divisions One and Two of the County Championship begin on Friday morning in the UK (Friday evening Australian time).
