The 22-year-old Central Coast Mariners forward has been rewarded for his international breakthrough with the Socceroos with an invitation to train at Upton Park for a week
The Premier League outfit have invited Duke to train at Upton Park with Sam Allardyce's squad and the Mariners have revealed that the 22-year-old striker will leave Australia on Saturday for a week with the London-based club.
Interest from West Ham follows Duke's Australia debut at the East Asian Cup last month, where he scored two goals and was one of only four players to start all three of the Socceroos' matches in the tournament in South Korea.
The powerfully-built forward had a breakthrough season for the Mariners during their 2012-13 A-League championship-winning campaign, scoring eight goals in 28 appearances in all competitions.
Central Coast expect Duke to return to Australia on August 17 but revealed in a statement that they would update fans and media with any further developments should they occur.
West Ham finished 10th in the Premier League last term and will kick off their new campaign at home against Cardiff next week.
The London club has had a strong connection with Australia in the past, with Richard Garcia, Hayden Foxe and Michael Ferrante all having spent time at Upton Park, while 19-year-old Australian forward Dylan Tombides is currently part of the Hammers' youth set-up.
