 One female passenger was taken to Royal Adelaide Hospital in stable condition. As many as eight passengers felt sick from the fumes.

 Initial reports were that the toxic fume was carbon monoxide, but Virgin Blue officials later denied that. They do not know what the odor was, or where it came from. 

 The flight had been going from Perth to Sydney when it was diverted after the odor was detected.
