Profit/Loss is an indicator of the overall performance of a business for a year. Its a direct measure of whether the company gained or lost ground financially during the period.
Cash flow is a measure of the companies ability to conduct its business, pay bills, repay loans, pay staff etc. This includes procedes from borrowings etc.
VAH made a loss last half, but it actually improved its cash position by about $200m with $933m worth of borrowings. As a result net long term liabilities increased accordingly.
The more liabilities you have the greater the cash position required to prove that business will continue to operate smoothly.
If you compare this to Rex for example the company operates with small cash reserves due to almost no debt position, positive cash is reinvested directly into the company.
