Galloway signed with the Central Coast Mariners during the 2016/17 season ahead of round three under Paul Okon. He has featured 24 times in Yellow & Navy.

The 22-year-old defender was scheduled to join Josep Gombau’s Olyroos in camp this week but has been permitted by both Football Federation Australia and the Central Coast Mariners to travel to Europe to trial with Willem II, a club who play in the Dutch Eredivisie.

The Central Coast Mariners will provide an update on Galloway’s playing future when he returns to Australia.
