Eastwood is currently sidelined with a knee ligament injury
Leeds have transfer-listed Greg Eastwood after the New Zealand international asked to leave because he cannot settle in England.
But the Rhinos will demand a £100,000 fee for the 23-year-old who joined them on a three-year contract this season.
The forward hopes to secure a deal with a club in Australia's NRL at the end of the campaign.
Head coach Brian McClennan said: "He gets on great with everyone but misses his family back home."
Leeds originally agreed to sign Eastwood from Brisbane Broncos in 2009 but visa complications delayed his arrival by a year.
He spent last season with Canterbury Bulldogs before joining the Headingley club at the start of this campaign.
I have found it tough without my family here in the UK
McClennan said: "It has been a difficult year for Greg. He is a young, single man which can make it difficult to settle down.
"He has had three injuries this year which has led to obvious frustrations but he has handled his last injury very well and is on his way back to full fitness."
Rhinos chief executive Gary Hetherington said: "Following a meeting between Brian McClennan and Greg Eastwood the player requested to be placed on the transfer list so he can speak to clubs in the NRL.
"Greg has two years remaining on his contract and therefore we will not be releasing him from that obligation and we value him at £100,000."
World Cup winner Eastwood said: "I have found it tough without my family here in the UK and that is the only reason that I want to return to the NRL."
