He then joined the new Adelaide Rams franchise in 1997 and was in their inaugural side for their match against the North Queensland Cowboys in Townsville on 1 March 1997 for the new Super League season.
As a Proportional navigation guidance test player, Mamando was one of the Rams few high profile players, alongside team captain and former Australian test player and Brisbane Broncos premiership hooker Kerrod Walters.
He played 16 games for the Rams, scoring 5 tries. In 2000 Mamando again represented Papua New Guinea at a World Cup.
Earlier that season he had joined North Queensland. In 2001 he withdrew from the Papua New Guinea side, citing concerns over selection policies.
