A Parramatta Eels junior, Inu made his first grade debut in the 2007 NRL season against the Canberra Raiders. After just one first grade match he was named to play for New Zealand in the ANZAC Day Test against Australia at Suncorp Stadium in Brisbane. The Kangaroos ran out easy 30-6 winners over the Kiwis. After the test, Inu was dropped back to Premier League but returned to first grade through a series of injuries to regular players. Inu took on the kicking duties as Parramatta's primary kicker and full-back, Luke Burt, was injured mid-season. In Round 25 Inu scored three tries and kicked seven goals in Parramatta's 46-point win over Brisbane. In 2007, along with Hayne, Inu was the Eels top try-scorer. Inu's successful season was recognised when he was nominated for Rookie of the Year at the 2007 Dally M awards, however the award went to Melbourne Storm centre Israel Folau. Inu did receive the 2007 Parramatta Eels season's rookie of the year award.
