1.2.3 Proposals and exploration

Summary

There are currently no proposals for the development of new coal mines within the Clarence‑Moreton bioregion. However, large areas of the Clarence‑Moreton bioregion in Queensland are covered by current coal exploration permits. At present, coal exploration occurs in the south-western Clarence‑Moreton bioregion in NSW, where Waratah Coal Pty Ltd is exploring the economic potential of the Nymboida Coal Measures for coal mining, and west of Ipswich, where Cuesta Coal is exploring the coal resources of the Amberley Deposit.

Coal seam gas (CSG) and conventional gas exploration occur in different parts of the Clarence‑Moreton bioregion in both Queensland and NSW. The major target of the CSG exploration is the Walloon Coal Measures, although exploration also tests the resource potential of the Ipswich Coal Measures. Recent CSG exploration campaigns have tested the economic potential of the Walloon Coal Measures throughout different parts of the Clarence‑Moreton bioregion. The largest number of CSG exploration wells has been drilled in the Casino Trough. The thickest accumulation of Walloon Coal Measures (>700 m), thick coal seams and the high gas saturation of the coal seams suggest that conditions for CSG development are favourable in this depositional centre.

Within the Clarence‑Moreton bioregion, the area near Casino currently appears to be the most likely for any CSG development to proceed.
