Fiji-born and raised Marika Koroibete first came to notice in Australia as an NRL star. Koroibete played six seasons in the NRL, with the Wests Tigers and the Melbourne Storm, scoring 46 tries in 74 games. In May 2016, the flying winger announced he would move to the 15-man game, signing with the Melbourne Rebels. Later that year, Koroibete was a surprise selection for the Spring Tour, playing for a Wallaby XV against the French Barbarians, but forced to wait for a Test debut. His patience proved more than worthwhile when Koroibete exploded onto the international scene halfway through the 2017 Rugby Championship, debuting against Argentina in Canberra.
Koroibete won his first Test cap off the bench against Argentina in Canberra, before being given his first start against South Africa in Bloemfontein and scoring a double. Koroibete finished the year with eight Test caps to his name.
He started on the wing in 11 of his 12 Tests, scored three tries, and only missed the 6-9 loss to Wales in Cardiff.
