Haggerty - the son of former St Helens forward Roy - has established himself as a key performer for Harlequins in Super League, frequently wreaking havoc against tiring defences from the bench.
And with great footwork and a surprising turn of pace for such a big man, Haggerty should be primed to prosper on the hard pitches out in Australia.
Other names to keep an eye on: Pat Richards; Michael Platt; Eamon O'Carroll
