The 22-year-old - who is heading to stage two of the DP World Tour Qualifying School next week - clinched the medal for his country with a birdie at the final hole, in his scheduled event as an amateur.
If it was possible to top his experience playing for Great Britain and Ireland in last month's Walker Cup - where he played foursomes with the son of Ryder Cup legend Ian Poulter against America in his adopted California home for the past two years, then finishing third behind South Africa and Australia, certainly gave Forster a huge sense of pride after walking off the last hole, having made the required four.

Charlie, from Basingstoke, said: "That was one of the best experiences over the last three or four years playing against some of the best players in the amateur game - both at home and abroad.
"England had a small but close team who made a lot of memories over the week in Singapore. It was a great time and way to end my England days.
"Playing the 18th hole on the last day was probably the best shot I hit over the four rounds. I had 275 yards uphill and an awkward stance and had to make birdie to win a medal. "I hit three-wood onto the green and made a two-putt birdie. It was a great feeling."
Forster and team-mates Tyler Weaver and Elliot Baker - who were both team-mates in GB&I's battling defeat at Cypress Point in the Walker Cup - were left up against it with a round to go after South Africa ended any hopes of a first gold medal for England since the Home Nations entered the Eisenhower separately in 2002.
With the best two scores in each team counting on all four days, England entered the final round trailing South Africa by 14 shots, with Christian Mass leading the individual scoreboard on 19-under.
But crucially they were three shots behind Australia and Mexico, who were tied in second place, after Forster and Co. posted 12-under after three rounds at Singapore's Tanah Country Club.
Maas ran away with the individual trophy after posting 22-under, but the battle behind the South Africans reached boiling point on the back nine, as England held their nerve to fire seven-under between Forster (70) and Baker (69) to overhaul the Mexicans and claim the bronze by two shots.
Forster revealed that England captain Ben Gorvett and team coach Rob Watts had instilled the mindset to be aggressive on the course which is set close to Singapore's Changi airport.
Charlie said: "We didn't have too many discussions as a group. The hardest part of the week was in practice, getting used to the grass and heat. "It was also tough to work out yardages and how far the ball went in the humid air. Ben and Rob just wanted us to be aggressive and make as many birdies as possible - pars weren't going to win anything on that course."
