The ill passengers were moved to seats at the rear of the plane near where four toilets were located, Australian Associated Press reported. Enright confirmed that the passengers were seated near the rear, but could not say whether they had been moved there by the cabin crew.
Qantas said other passengers were advised to keep a close eye on their health over the next two days and to seek medical advice if they feel ill.
Enright declined to say how many passengers were on the flight. AAP reported that more than 300 passengers were aboard, without citing a source.
