The troubled Rio de Janeiro Olympic Games have arrived at their first major crisis, less than two weeks before the opening ceremony.

The Australian Olympic Committee confirmed on Sunday evening that the athletes' village has been deemed uninhabitable in the short term due to significant plumbing and electrical concerns.

It is unclear if and when competitors will be able to move in, with the International Olympic Committee is set to undertake "stress tests" to deal with serious issues with plumbing and fire safety.

AOC chef de mission Kitty Chiller confirmed late on Sunday night (AEST) that Australian athletes would not be moving into the village, having hoped to do so on Sunday.
