Sloan allegedly collapsed on September 1st and was in a coma when he died at 1pm (AEST) yesterday at a Beijing hospital.
Sources told ninemsn.com.au that drugs may have played a part in the 34-year-old's death, but it has not yet been confirmed whether this was due to an overdose or being deliberately drugged by another person.
It was confirmed by the Department of Foreign Affairs that a New Zealand-born Australian citizen from Victoria died in Beijing yesterday.
Sloan's parents, who are based in New-Zealand, and his brother and sister, flew to Beijing yesterday but declined to comment.
One of the housemates in the first series of Big Brother, Sloan was evicted after 35 days. Fellow contestant Ben Williams went on to win the series.
