Qantas Airways shares have fallen below one Australian dollar for the first time since the carrier went to the markets in 1995.
The sharp fall comes after ratings agency Standard & Poor's put the airline on review for a possible downgrade.
The airline has struggled with slowing demand and higher fuel prices, as Duncan Kennedy reports from Sydney.
