Rehabilitation case studies
Newlands is located 33 kilometres north-west of the township of Glenden in the northern part of the Bowen Basin, Queensland. It includes an open cut and longwall mining operation, producing steaming coal and coking coal for export markets via the Abbot Point Bulk Coal export terminal.
Throughout 2016 and 2017, Glencore worked collaboratively with the Department of Environment and Heritage Protection (now Department of Environment and Science) to certify rehabilitated land associated with part of an overburden emplacement area. The mined land was progressively rehabilitated in three sections over 19 years ago (in 1995, 1997 and 1998) to habitat suitable for flora and fauna.
On 2 June 2017, 73.48 hectares of rehabilitated land was certified by the Queensland Government. At the time of approval, Newlands was the first open cut mine in the State to receive certification. This milestone marked a significant achievement and provided a constructive way forward for both Government and the mining sector in encouraging further certification of progressive rehabilitation.
Rolleston is located in the southern part of the Bowen Basin, approximately 16 kilometres west of the Rolleston township and 140 kilometres south-east of Emerald in Queensland. It is an open cut operation producing low ash content thermal coal for export via ports in Gladstone or the domestic market.
Rolleston is committed to progressive rehabilitation with the objective of returning land disturbed by mining primarily to pasture for livestock grazing. As operations advance, mined land is rehabilitated with native tree species, and native and improved pasture grass species.
On 25 June 2018, 220.6 hectares of rehabilitated land was certified by the Queensland Government. The area was progressively rehabilitated between 2007 and 2015 and includes a trial area of 10 hectares to establish Semi-Evergreen Vine Thicket. On 22 November 2019, a further 166 hectares was certified adding to Glencore’s growing portfolio.
Watch how the team at Rolleston has made the transformation.
Collinsville is Queensland’s oldest coal mine having operated for almost 100 years. It is located in the northern part of the Bowen Basin, approximately 270 kilometres south east of Townsville in Queensland. Open cut operations produce a variety of coking and steaming coal products for both overseas and domestic markets.
As operations advance, mined land is progressively rehabilitated to pasture grass species with the post mining land use for Collinsville being grazing. Between 2012 and 2019, the site had rehabilitated more land than it has disturbed for mining.
On 15 October 2020, 99.5 hectares of rehabilitated land was certified by the Queensland Government. The team at Collinsville have also collaborated with a neighbouring private landholder to use this area for cattle grazing.
Oaky Creek, Glencore
Oaky Creek is located in Central Queensland’s Bowen Basin, 90 kilometres north-west of Emerald and 46 kilometres south-west of Middlemount. Open cut operations ceased in 2006 while underground operations continue to produce metallurgical coal for export.
Previous open cut mining areas have been rehabilitated and transformed into a landscape supporting mature and sustained (demonstrated species reproduction from seeding) native vegetation with the potential for cattle grazing. On 16 December 2020, 132.8 hectares of rehabilitated land was certified by the Queensland Government.
The team at Oaky Creek continues to work on achieving completion criteria for other areas of rehabilitation across the site. In striving towards this and future certification applications, another 369 hectares of rehabilitation was undertaken in 2020.
Wilkie Creek, Peabody
Wilkie Creek is located within the Western Downs Regional Council, approximately 40 kilometres west of Dalby and approximately 12 kilometres west of Macalister township in south-east Queensland. It was an open cut mine producing low sulphur, low nitrogen, and lower emissions thermal coal. At the end of 2013, Peabody announced the cessation of coal mining operations.
The team at Wilkie Creek has transformed land disturbed by mining into a rehabilitated landform tried and tested for pastoral activities in collaboration with local landholders. Consultation with these neighbours informed the levelling and reshaping of the final landform, soil quality and appropriate pasture species.
Peabody’s efforts were later recognised, on 8 February 2019, with 86.67 hectares of rehabilitated land certified by the Queensland Government.
Watch how the site is being transitioned to the next land use.
Millennium is on target to complete its rehabilitation of mined land two years ahead of schedule (by 2020) demonstrating the operation’s commitment to its environmental obligations and long-term sustainability.

New Acland, New Hope Group
New Acland is located north-west of Oakey in Queensland. Operations commenced in 2002 and the mine produces thermal coal.
Mined land is progressively rehabilitated to pasture. Once established, the land is segregated from mining activities and transferred to the management of Acland Pastoral Company who oversee grazing and cropping activities. During drought conditions, the rehabilitated land has provided a significant aid for pastoral operations. New Acland’s approach to rehabilitation has demonstrated successful co-existence of mining and agriculture.
On 1 November 2018, 349 hectares of rehabilitated land was certified by the Queensland Government. This adds to New Hope Group’s portfolio in leading environmental practices, including being awarded the 2016 ABA100 Winner of the Australian Business Award for Sustainability for scientific cattle grazing trials on rehabilitated land among other matters.
Watch how the team at New Acland have transformed the site and successfully demonstrated the co-existence of two land uses.
Dawson Mine, Anglo American
Anglo American continues to pursue best practice mine rehabilitation across its business, including at Dawson Mine. This operation has been leading the way in innovative rehabilitation approaches, such as blasting techniques to reshape void highwalls, to achieve a post-mining landform for future use with the focus being grazing.
Learn more about how the team at Dawson Mine are rehabilitating the site and transforming it to the next land use.
Gregory Crinum, BHP Mitsubishi Alliance
Gregory Crinum was owned and operated by BHP Mitsubishi Alliance (BMA), a joint venture between BHP and Mitsubishi Development Pty Ltd, until 27 March 2019 when the sale of the site to Sojitz Corporation was completed. Gregory Crinum is a hard, coking coal mine located 60 kilometres north-east of Emerald in the Bowen Basin, Queensland. In 2016, production ceased and the site was placed into care and maintenance.
BMA had undertaken a broad scope of restorative works to rehabilitate the land both during the course of its mining activities and after they had ceased, from closing exploration boreholes and cracks to removing surface infrastructure, ripping ground to encourage regeneration of vegetation and re-shaping the landscape to make it more suitable for re-use. Some of the rehabilitated land is now being used for a mix of grazing and cropping by neighbouring landholders.
On 16 October 2018, 1,176 hectares of rehabilitated land related to previous underground mining was certified by the Queensland Government. At the time, this represented the largest tract of mining-affected land ever certified by the State.
Norwich Park, BHP Mitsubishi Alliance
Norwich Park is a hard, coking coal open cut mine located 25 kilometres south-east of Dysart and 256 kilometres south-west of Mackay in the Bowen Basin, Queensland. In 2012, production ceased and the site was placed into care and maintenance.
BHP Mitsubishi Alliance has undertaken a broad scope of restorative works to rehabilitate the land both during the course of its mining activities and after they had ceased, from re-shaping the landscape, ripping, ameliorating, spreading topsoil and seeding to encourage revegetation to make the land suitable for its agreed post mining land use. Some of this rehabilitated land is now being used for grazing by neighbouring landholders. On 7 February 2019, 294 hectares of rehabilitated land was certified by the Queensland Government.
