It provides a timely boost for the Cumbrian club, who will start the new season on minus nine points after entering adminstration at the end of the last campaign, following a 50-0 pre-season friendly hammering at the hands of league rivals Oldham on Sunday.
Head Coach David Seeds said: “We have been on the look-out for players and Luke was really keen to come over here and test himself.
“I don’t know much about him, but he has a very good CV. He’s experienced in a good competition in Australia.
“He has come over here to better himself and put himself in the shop window, and hopefully he’ll be a success for us. Prop is a key position and we’ve been pretty light on them.”
