Shares in Qantas fell to their lowest level ever on Tuesday as investors continue to desert the company because of its financial woes.
Qantas shares were worth A96.5 cents at the close of trade, below a previous all-time low of A97 cents in June 2012.
The shares dropped three cents on Tuesday, their fourth consecutive day of losses since the airline said it would make a $A300 million loss in the six months to 31 December.
AAP reports the company's market value has fallen by $A527 million in that time, to $A2.12 billion.
It was worth $A4.17 billion less than nine months ago.
Standard & Poor's lowered the airline's credit rating as a result of its profit warning, which will increase the costs of funding and leasing expensive aircraft.
