He then returned to Sydney, and joined South Sydney Rabbitohs, where he would remain for six seasons. At the end of the 1932 NSWRFL season, Lewis' first in the top grade,[4] he played in the premiership Final for Souths, scoring a try in their 19–12 victory over Western Suburbs.

Post-playing
After returning from war duties in early 1945, Eric Lewis stepped in to coach Souths for the 1945 NSWRFL season at a time when many players and coaches were absent because of the war. The South Sydney Rabbitohs line up was so disrupted, that no constant club captain was named during the season. Often, the captain was named on game day depending on who was available to play. The club only won one game during 1945.[6]
In Papua New Guinea during World War II, Lewis spotted Jack Rayner playing inter-regiment rugby league on a muddy field at Port Moresby and invited him to trial with South Sydney when he got home.[7] Rayner went on to captain and coach Souths, becoming an important figure in the club's history.
Lewis was long time resident of the Baine family's Dolphin Hotel in Surry Hills, New South Wales and lived there until his death which was widely mourned by South Sydney fans. He was buried at Botany Cemetery on 20 April 1959.[8]
