The 21-year-old Eastwood, who has made 62 appearances in Australia's National Rugby League for Brisbane Broncos, has agreed a three-year contract starting in 2009, when Ellis will be plying his trade with Wests Tigers.

Rhinos coach Brian McClennan, who as Kiwis boss gave Eastwood his debut in the Anzac Test of 2006, said: "He is still only 21 so that means that we are getting a player who has huge potential and is at the early stage of his career. His style will suit the Rhinos."

McClennan added: "He is a quiet and humble lad who will fit in well with our players.

"He is very skilful and has great versatility, having played on the wing, centre, stand-off and second row for the Broncos and has even filled in at dummy-half, despite being 105kg, at times this season."

Eastwood will link up with the Rhinos after the World Cup in Australia.

"I am really excited about joining Leeds Rhinos and coming to England," he said.

"I am looking forward to linking up again with Brian McClennan after he gave me my debut for the Kiwis.

"We watch the games from Super League on TV here and the Rhinos play a really good style of rugby which I think will suit my own game."
