BHP BILLITON ANNOUNCES GAS DISCOVERY AT THEBE-1 OFFSHORE AUSTRALIA              
BHP Billiton announced today a discovery at the Thebe-1 exploration well that   
was recently drilled offshore Western Australia. The well and subsequent        
evaluation confirmed a gas column of approximately 240 feet (73 metres)         
encountered in the Exmouth Plateau of the Carnarvon Basin.                      
Drilling of the Thebe-1 well began during the first week of July 2007 in block  
WA-346-P using the semi-submersible rig Atwood Eagle. The well is located       
approximately 186 miles (300 kilometres) off the North West coast of Western    
Australia in water depths of 3,848 feet (1173 metres). The well has now been    
abandoned after reservoir core was collected.  BHP Billiton is the operator at  
Thebe-1 and holds a 100 percent interest in the field.                          
"The Thebe discovery is an excellent addition to our global portfolio. The      
results are encouraging and we will now proceed with further data gathering and 
evaluation," said Steve O`Rourke, President of Global Exploration for BHP       
Billiton Petroleum.                                                             
Thebe-1 is the second significant BHP Billiton gas discovery in the basin and is
located approximately 31 miles (50 kilometres) north of the Scarborough gas     
field in which BHP Billiton is a 50 percent partner with ExxonMobil.
