Sanchez William Genia (born 17 January 1988) is a professional rugby union player, currently playing scrum-half for the Kintetsu Liners in Japan.

[2] His older brother, Frank Genia, plays international rugby union for Papua New Guinea Pukpuks .

[1][5] Despite playing 110 tests for Australia and having lived in Australia since he was 12, Genia does not hold Australian citizenship, owing to him playing professional rugby union overseas and the legal requirement for applicants to not have been absent from the country for more than 12 months in total in the four-year period, including no more than 90 days in total in the 12-month period prior to application.

He was selected as the first choice scrumhalf for the Australian Under 20 team for the 2008 IRB Junior World Cup in Wales.

[12] Genia was selected in the Wallabies squad for the 2009 Tri Nations and made his test debut against the All Blacks at Eden Park in Auckland on 18 July 2009.

[16] In early September Genia suffered a knee injury in Australia's win over South Africa.

Genia missed eight Tests in a row and didn't expect to return to domestic action until the Reds play the Bulls in Brisbane on 23 March 2013.
