Packer's primary schooling suffered greatly when he was struck with a severe bout of
poliomyelitis at age eight, and he was confined to an
iron lung for nine months. His father apparently thought little of his son's abilities, once cruelly describing him as "the family idiot", although Kerry subsequently steered
PBL to heights far beyond anything his father or brother achieved. The nickname his father gave Kerry made him strive to new heights in schooling, trying to achieve "A" grades. His end of year report said he was one of the most notable students. In an interview, former employee
Trevor Sykes stated that "He didn't read much on the printed page. If you didn't want Kerry to read something, you wrote more than a one-page memo." Packer's grandfather
Herbert Bullmore represented the
Scotland national rugby union team in an international match against
Ireland in Dublin in 1902 and worked as a doctor in Sydney for many years. Kerry Packer and his wife of 42 years,
Roslyn Packer (
nee Weedon), had two children: a daughter,
Gretel, and a son, James. At the time of Packer's death, he and Ros had two grandchildren: Francesca then 10, and Ben, then 7, from Gretel's first marriage to British financier Nick Barham, and Gretel and her husband Shane Murray were expecting their first child together, William (born 2006). Gretel and Shane married just before Packer's death. Packer conducted extra-marital affairs with a number of women including the model Carol Lopes, who reportedly committed suicide after being shunned by Packer; publisher and former ConPress employee
Ita Buttrose and Julie Trethowan, his long-time mistress and manager (from 1983) of the Packer-owned Sydney city health and fitness club, the Hyde Park Club. After his death,
The Sydney Morning Herald reported that from about 1995, Packer transferred control of multimillion-dollar Sydney real estate holdings to Trethowan. In June 2009, the
Sydney Morning Herald reported that former
federal opposition leader and future Australian Prime Minister,
Malcolm Turnbull, a former legal adviser and business associate of Packer, revealed to journalist
Annabel Crabb that Packer had threatened to have him killed when they fell out over their 1991 attempt to take over the Fairfax newspaper group through their Tourang consortium. Packer reportedly made the threat after Turnbull told Packer he was going to have him thrown out of the consortium by revealing Packer's intention to play an interventionist role in the newspaper group. Packer was a supporter of
South Sydney Rabbitohs in the
National Rugby League competition. He was an advocate of the
Australian Republic Movement.
Polo Packer was a keen
polo player. In 1992, he and
Gonzalo Pieres Sr. founded Ellerstina, a polo team that has claimed multiple titles at the
Argentine Open and other high-handicap tournaments. Packer bought the
Fyning Hill estate in West Sussex and expanded it to over 400 acres. Packer built the headquarters for his Ellerston polo team at Fyning Hill, and would arrive at the estate in May for the three-month English polo season. Packer sold the estate to the Russian businessman
Roman Abramovich in 1999 for 12 million.
Gambling Packer was a long-time heavy smoker and an avid gambler, fabled for his large wins and losses. In 1999, a three-day losing streak at London casinos cost him almost A$28 million – the biggest reported gambling loss in British history. Once he won A$33 million at the
MGM Grand Casino in
Las Vegas, and he often won as much as A$7 million each year during his annual holidays in the UK. Packer's visits were a risky affair for the casinos, as his wins and losses could make quite a difference to the finances of even bigger casinos. Packer was also known for his sometimes volcanic temper—and for his perennial contempt for journalists who sought to question his activities. Packer is quoted for an exchange in a poker tournament at the
Stratosphere Casino, where a
Texan oil investor was attempting to engage him in a game of poker. Upon the Texan saying "I'm worth $60 million!", Packer apparently pulled out a coin and asked nonchalantly, "heads or tails?", referring to an A$120 million wager (according to
Bob Stupak's biography). Some variations of the story put the sum at A$60 million to A$100 million and say the line was "I'll toss you for it". In the late 1990s, he walked into a major London casino and played £15 million on four roulette tables on his own and lost it all. This has been confirmed by casino owners in South East England. Former PGA professional
John Daly said on the
Full Send Podcast that Packer closed down the
Desert Inn Casino (which was replaced by the
Wynn Hotel) by winning 52 million dollars in one day and insisting they pay him in cash, as the previous day when he lost 8.2 million dollars they insisted he pay them in cash. The
Ritz Hotel in London even had its own room for Kerry Packer. There he was able to play blackjack with a minimum bet of £10,000 per hand. He once lost more than £19 million in this room. ==Failing health==
