Batsman Callum Ferguson rejoins Worcestershire in Division Two of the championship after a stunning campaign last year.
Ferguson starred in the limited-overs formats after signing as a replacement player for fellow South Australian Travis Head, smashing a record-breaking 192 in his debut innings for Worcestershire in the Royal London One-Day Cup.
He went on to notch another century in the following match and was the county’s second-best One-Day Cup runscorer, averaging just over 94, despite playing just five matches.
Ferguson continued his rich form with another ton and two half-centuries in the UK’s Vitality Blast T20 competition.
He’ll be joined by fellow Redback Daniel Worrall in Division Two as the swing bowler resumes with Gloucestershire.
Injury cut Worrall’s maiden county campaign short last summer, but he still impressed with 16 wickets at 21.75 with an economy of just 2.92 from four first-class outings.
Worrall will be looking to put a luckless run of injuries behind him with the 27-year-old’s bowling style well-suited to English conditions and the swing-friendly Dukes ball.
Australian representative Adam Zampa has also re-signed with Essex for the Vitality Blast T20 competition after this year’s World Cup.
Zampa was the Eagles’ top T20 wicket-taker in the competition last year, taking 12 wickets in 10 matches.
Fellow Australian bowler Kane Richardson will also feature in the T20 blast, joining Derbyshire for his first UK county stint.
Richardson was the leading wicket-taker of the KFC Big Bash League with champions Melbourne Renegades after claiming a tournament record 24 wickets from 14 matches.
Several other Redbacks, including Jake Weatherald, Nick Winter and Jake Lehmann, are also tipped to play club cricket at different stages of the UK summer.
First-class cricket kicks off England’s domestic season with the first round of the Specsavers County Championship from Friday, 5 April.
The Royal London One-Day Cup follows from Wednesday, 17 April and the Vitality Blast T20 competition begins on Thursday, 18 July.
