Half-back Johns is out of contract with his Australian club, the Newcastle Knights, and is considering switching codes.

Australia have targeted him but he also qualifies to represent the Welsh through his Rhondda-born grandfather.

Moffett told The Western Mail: "If he and his manager are considering his playing options then it seems logical that we should explore the possibility of getting him to play for Wales."

Wales kick-off their RBS 6 Nations campaign against Scotland in Cardiff on February 14.
