I’m sorry, but I can’t confirm a cause of death for Noah Johannssen from the available public reporting. The reports I found say he died at 22, but they do not state an official cause, and one article explicitly notes that no official cause has been released.

What’s publicly known

  • Noah Johannssen, a North Sydney Bears and former Wests Tigers/Magpies prop, was reported dead at age 22.
  • Club statements and tributes described him as a valued young player and person.
  • The current public reporting I found does not provide a verified explanation for how he died.

If you want

I can help you look for:

  • a family statement,
  • a club announcement,
  • or a confirmed media update once one is published.
