Austral Pacific reports results of A6 Well Drilling and Notification of
Waihapa Production Station temporary shut down

The current well program was designed to test additional reserve potential in
the greater Cheal area. The locations were chosen, based on the regional 3D
seismic data set to have potential for a thick gross sand package, above the
regional oil water contact.

Cheal-A6 and A6ST wells were targeting a separate lobe of sand from the main
Cheal 'A' Pool, the Cheal-A7 well is classified as a step out well targeting
an extension to the same pool as the successful Cheal A3 and A4 wells.

The company announces that the Cheal-A6 well reached a total depth of 1930m
on June 26th, 2008. The well intercepted an oil bearing MM3 Formation as
prognosed at approximately 1818m MD, but the net sand interval was
interpreted from electric logs to be some 2 metres thick, thinner than
prognosed and sub economic to complete and produce.

The Joint Venture (Austral Pacific Energy Ltd 69.5% and TAG Oil 30.5%) agreed
to plug and abandon the MM3 zone in this well bore, set a whipstock plug at
1359m and kick off a side track well to a targeted location approximately
150m to the south of the original A6 penetration.

Cheal-A6ST was drilled to a total depth of 1936m on July 2nd, 2008 and
intercepted the targeted MM3 sands as prognosed, well above the regional
oil/water contact, but again, while oil charged they were only some 2 meters
thick. After evaluation of all subsurface data the Joint Venture has agreed
to plug and abandon the A6ST well as a sub-commercial hydrocarbon discovery.

A new whipstock plug will be set in the wellbore and the rig will now
commence drilling the Cheal-A7 well from the same surface location.

Commenting upon the result, Mr Jewell Austral CEO said "we were pleased with
proving that the oil water contact encompassed a larger Cheal field area but
very disappointed that the aggregate sand thickness in this location was too
thin to be commercially produced. While we are disappointed in the results in
this well we remain confident in the ultimate upside potential of the Cheal
field development and the Greater Cheal play trend. We have built well
appraisal failures into our overall planning and remain determined to bring
success to the JV and shareholders."

In other news Austral has been informed by Origin that the Waihapa Production
Station is being temporarily shut down due to inadequate supplies of gas to
the facility from other sources. The Cheal field oil production produces very
small volumes of gas; most of which is used to operate the plant and generate
electricity into the grid. The minor amounts of residual gas, some 150,000
cubic feet per day, is processed at the Waihapa Production Facility and sold
to Vector and carried to market through the Vector gas transmission network
system.

As a result of the shut down, Origin has now informed Austral that the
processing of raw gas from Cheal into the Waihapa Production Station has been
suspended. Origin has proposed an option to allow the Cheal field to continue
producing at optimum rates and reinject its spare gas into one of its
existing reservoirs. Austral and Origin are working together to formalize an
agreement.

Commenting on the Waihapa Production Station shut down Mr Jewell said "access
to market for both the gas and oil production from our Cheal field is
critically important to the company so we maintain plans to support multiple
contingencies. The field is capable of producing up to 1million cu feet of
gas per day but currently only 150 thousand cu feet are excess to the Cheal
plant operations. Our current production of 420 barrels per day continues."
