My sister knew something was wrong when mum started crying while she was reading Australian golfer Jason Day has been left devastated by the news eight Philippines-based family members were killed in Typhoon Haiyan. Jason Day: 'The family has lost everything. It's really hard to put into words the loss you feel.' JASON Day was inconsolable over his family's agony as the Typhoon Haiyan tragedy hit home. Day, in Victoria for the World Cup of Golf at Royal Melbourne, wept on Monday as he contemplated his mother's pain at the loss of his grandmother and at least seven other relatives in the Philippines killed in last week's super storm. Day yesterday revealed his mum, Dening, had agonisingly learnt of the deaths of her mother, brother and six children as she deciphered a facebook page written from Manila as her family's desperate search for more survivors continues around the worst hit regions around Tacloban. "My sister knew something was wrong when mum started crying while she was reading ... it's just so hard comprehend," Day said. It's horrible. I just really feel for my mum, it's so hard not to be with her. I just want to give her a hug and make sure she's OK. She's lost so much; the family has lost everything. It's really hard to put into words the loss you feel. Dening emigrated to Australia more than 30 years ago, but had been planning a return visit later this year before the tragedy struck last week. Day, who flew into Melbourne from his US home late last week, will have a teary reunion with his family when they fly from Brisbane to watch him play for Australia for the first time. Day, who hadn't met his Philippines family face to face, said his mother had urged him to play on with Adam Scott for a cause that they both hold dearly. "I get to spend my quality time with my mum ... and as much as I'm really keen to do well for Australia at the World Cup, it's more about her this week," he said. She said she didn't want to bother me too much, but I just want to be there for her as much as I can. Of these cousins of golfer Jason Day, five were killed in the Philippines typhon. It's been real tough on my mum. There's no (direct) communications to our family up there (because) everything got wiped out. I'm usually so far away from home and you feel helpless, but I think it's really going to be good for us all to be together here in Melbourne so we can ... do what families do. The world golf community, through its Federation of Tours, intends to rally around the victims of the killer typhoon this week at Royal Melbourne, with fundraising initiatives at the club and on global television. "We are looking into the best way that we can show support for those affected," US Tour executive Matt Kamienski said last night. With the ISPS HANDA World Cup of Golf standing as a global event and serving goodwill through the game, we certainly want to drive awareness to the relief efforts. Jason Day's sister, Kim, with their grandmother (lola) Adelaida, who was killed in the Philippines typhon. PGA of Australia chief executive Brian Thorburn said he'd fielded "numerous enquiries" from players and others offering assistance. "We'll be working with the Federation to do all we can to support the relief effort as well as Jason and his family," Thorburn said.
