Gunther was a strong tackling flanker and played his rugby in country New South Wales, much of it with Molong.[2] He gained his first Wallabies call up in 1957 for a home series against the All Blacks. After Chilla Wilson was preferred for the 1st Test, selectors made four changes up front for the 2nd Test in Brisbane, with Gunther earning his solitary Wallabies cap.[3] He made 15 uncapped appearances on the 1957–58 tour of Britain, Ireland and France.[1]
