The study, which was commissioned by organizers of The Bingham Cup, the world cup of gay rugby, is being conducted by sports research firm Repucom in consultation with researchers from 6 universities.

Also appearing in the video are British-born rugby stars Sam and Tom Burgess, soccer player Sarah Walsh, rugby player David Pocock and Australian football star Brock McLean

In 2011, Pocock made headlines around the world when he pledged not to marry his fiancee until gay and lesbian couples are allowed to marry in Australia.
