A graduate from the infamous Bishops school, South African Koster is a powerful ball carrying loose forward by trade.
Hailing from Robertston in South Africa, Koster made his debut in the Currie Cup for Western Province in 2008 and was later that year picked for the Barbarians side to play at Wembley against Australia.
Four years after making his debut for WP and representing the Stormers on over 30 occasions, Koster decided to sign a deal with Bath.
After a short stint with Bath, Koster signed with Bristol in 2014 and spent 3 years at the club before being released at the end of the 2016/17 season.
Koster joined Cornish Pirates for the 2017-18 Championship season.
