Left-hander to play for Welsh county in 2018, joining younger brother Mitch on the county circuit
Marsh signs two-year Glamorgan deal
Shaun Marsh has joined younger brother Mitch in signing on for next year's English domestic season, with Glamorgan announcing the Test batsman as their overseas player for 2018 and 2019.
The elder Marsh has penned a two-year deal with Glamorgan, re-joining the Welsh county following a stint with them in 2012.
"I'm extremely excited to be joining Glamorgan," Marsh told the club's website.
"I have some great memories of the club when I played in Cardiff in 2012 and I'm glad to be back.
"Securing my county future for the long term has always appealed to me, so I jumped at the opportunity when it came."
The left-hander has played 23 Tests, 52 one-day Internationals and 15 Twenty20 games for Australia and is in the 13-man squad for the first two Tests of the Magellan Ashes series.
After a T20 spell at Glamorgan in 2012, Marsh played for Yorkshire last season.
EMBED:The 34-year-old will be available for the full 2018 county season, subject to the Indian Premier League draft.
Glamorgan will sign another overseas player to cover the period of Marsh's absence if he is signed by an IPL team.
"We wanted to bring in someone who is experienced at international level, can bat at the top of the order and can play in all three formats of the game, and Shaun ticks all of those boxes for us," said Glamorgan director of cricket Hugh Morris.
"He is a world class performer who has played in competitions across the world and that experience will be invaluable to our young players as we look to build on our success in white-ball cricket and improve performances in the county championship."
Mitch Marsh last month confirmed he would forgo next year's IPL and will instead play all three formats for Surrey following the conclusion of the Australian domestic season.
The allrounder is set to link up with former Australia batting mentor and current Surrey coach Michael di Venuto.
He has sizable shoes to fill as the team's overseas player; Sri Lanka legend Kumar Sangakkara last season struck a County Championship-leading 1,491 runs at 106.50 including eight centuries for Surrey.
