MOTORISTS have been warned to expect disrupted petrol supplies in Brisbane this weekend.

A leaked email from the State Government to the Ambulance Service, obtained by couriermail.com.au, said the shortage of unleaded petrol suffered by Caltex, Shell and BP is expected to lead to long delays at the pump, higher prices and possibly complete unavailability at some service stations.


Particularly affected, the email said, will be the greater Brisbane and Mackay areas.

The shortages would only remain "short term, the email said, with supplies expected to "return to normal within a few days".
