Roc Oil (WA) Pty Limited, a wholly owned subsidiary of ROC, is pleased to
announce the commencement of a two well exploration/appraisal drilling programme
in WA-286-P, in the North Perth Basin, offshore Western Australia.

At 0100 hours (local time) on 3 February 2008, the Premium 'WilCraft' jack-up
drilling rig commenced drilling the Lilac-1 exploration well, in 33 metres of
water approximately 2.5 kilometres east of the Dunsborough-1 oil and gas
discovery made in the permit in June 2007.

Lilac-1 is expected to reach a Total Depth of approximately 1,435 mBRT in
mid-February, 2008.

As of 0600 (local time) on 4 February 2008 the current operation was preparing
to run 13-3/8' casing.

Following the drilling of Lilac-1, an appraisal well, Frankland-2, also in

completed by the end of February 2008.

Chief Executive Officer, stated that:
