SYDNEY, Dec 16 (Reuters) - James Packer, the majority owner of Australia's Crown Resorts Ltd CWN.AX , is in talks with private financiers about a possible buyout of the casino giant, two media reports said, sending the company's shares on their biggest one-day spike.
A buyout would be a relief for shareholders who have watched their investment shrink by a third in two years as a Chinese corruption crackdown hits gambling revenues in Macau.

The Australian newspaper said Packer, who owns 53 percent of the A$8 billion ($5.8 billion) firm, was in talks with U.S. private equity giant TPG Capital Management LP TPG.UL and unnamed pension funds about the possibility of taking Crown private.
A TPG spokeswoman denied that the private equity firm was involved in the discussions.
Citing unnamed sources, Bloomberg said Packer's unlisted Consolidated Press Holdings Pty was in discussions with financing partners about returning some of Crown's casino assets to private ownership.
A Crown spokesman was not immediately available for comment.
Following the reports, Crown shares rose as much as 14 percent in Sydney trading, their biggest gain in a single session. They hit a four-month high of A$12.23. Melco Crown shares were up 2.5 percent.
For Packer, a buyout would allow him to ride out the Macau downturn which has seen gambling revenue fall for 18 months straight.
"We think (Crown) is pretty undervalued, and as a proprietor it looks like he has the same view," said Morningstar analyst Brian Han.
"It has a lot of forward expansion projects in the pipeline and the balance could be stretched, but on the other hand, Macau will come back."
The move would round out a year of change for Packer's relationship with Crown, the media company he took over from his late father in 2005 and transformed into a multinational gambling chain.
In August, Packer unexpectedly quit as chairman without giving a reason.
A Nov. 10 filing to the Australian Securities Exchange showed Packer bought nearly 22 million Crown shares, worth about A$260 million at the time. urn:newsml:reuters.com:*:nL3N10O01I ($1 = 1.3881 Australian dollars)
