Tragedy struck former Blues coach David Nucifora and his family when his daughter Katie passed away just days before Christmas.
The 21-year-old Brisbane native moved from the Gold Coast to Sydney late last month.
She died on December 20, and a funeral service will be held on Friday, according to a widely-shared post on social media.
Dad David played two tests for Australia in the early 90s and has been based in Ireland since his appointment as Performance Director of the IRFU in 2014, with local media describing him as "one of the most powerful men" in Irish rugby.
