A contemporary rehabilitation program

The Sunnyside open-cut mine was operational from 2008 until 2012, when it was placed into care and maintenance. ​​

The mine resumed operations in the second half of 2017 with the aim of mining the remaining coal and fully rehabilitating the site. Coal sales from the mine will effectively fund the full and final rehabilitation of the mine site, providing a contemporary example of a rehabilitation program to the local community.

Sunnyside mine
Before mining, the area had been cleared for agricultural cultivation and grazing, with a predominantly cropping and pastoral land use.

The rehabilitation process is intended to return the site to pastures in the flat areas (approx. 54.43 ha) and woodland (approx. 35.3 ha) on the slopes, to reflect the surrounding vegetation. While the majority will be agricultural land, the rehabilitation strategy also includes enhancing biodiversity – in particular, some areas that were not disturbed by mining are being planted with tree species used by koalas to create movement corridors between separated woodlands. Key activities until about 2025 include maintenance of the landform to ensure it is safe and stable, and to control feral animals and weeds.

Future Planning

The final year of mine operations

Mining at Sunnyside is expected to be completed during FY20. Rehabilitation is also occurring progressively, with final shaping of the landform and planting to be undertaken following the conclusion of coal mining. A Closure Mining Operations Plan has been approved to support the mine’s rehabilitation.
