Australia seamer Michael Neser will join Surrey for the first half of the 2020 County Championship campaign.
The 29-year-old was part of the Ashes squad in the summer but did not feature and is yet to make his Test debut.
The South Africa-born bowler played two One-Day Internationals for Australia in 2018 against England and averages 26.43 with the ball in first-class cricket.
“It has been a long held ambition of mine to play county cricket,” Neser told Surrey’s website.
“To be able to do so at The Kia Oval alongside some fabulous players is obviously hugely exciting for me.”
Neser will play for the 2018 county champions until early July.
