national park. Conservationists foresaw there existed a strong argument that further mining would have been totally inappropriate, given regard for future and continuing land uses and therefore the lease ML1117 could not be renewed under the Mineral Resources Act. Under Queensland law, a ministerial decision to renew ML1117 would have allowed a right to judicial review of the decision in the Queensland Supreme Court by indigenous owners, the Quandamooka people of NSI, and conservationists. These parties had publicly flagged they would certainly use that right, given the good prospects of overturning the lease renewal decision upon judicial review, and bringing about the cessation of sand mining on the island around 2014. In response to the public debate, and to the very real likelihood that expired mining leases would not be successfully renewed under the Minerals Resources Act if proper regard was given to future land use, on 22 March 2011 then Premier Anna Bligh announced that the Enterprise Mine would continue the operating until 2019, the Yarraman mine would operate until 2015 and the silica mine (Vance) until 2025. The Queensland government would approve sand mining on North Stradbroke Island not through considering an application for renewal of a mining lease under the Mineral Resources Act, but through the passage of a new Act, the Stradbroke Island Sustainability and Protection Act 2011 (NSI Act). This Act was passed in April 2011. The act renewed the key expired Enterprise Mine mining lease ML1117 until 31 December 2019 and also extinguished the pre-existing judicial rights of conservationists and Indigenous owners opposed to renewal of the leases. The act also renewed two expired leases to facilitate continued silica sand mining at Vance until 2025. Under the State Government's Stradbroke Island Sustainability and Protection Act 2011, 80% of the island will become national park by 2026. The national park will be jointly managed by the Quandamooka people under the Indigenous land use agreement. The State Government planned to develop tourism opportunities by creating new walking tracks, camping grounds and recreational facilities. However, economic modeling undertaken by consultants commissioned by Sibelco Australia, Synergies Economic Consulting, states the growth in labour demand from tourism expansion is not expected to be rapid. This was because, at the time of the report in 2011, there was an overall weakness in domestic tourism across Australia. Under the 2011 legislation, the Enterprise mine was to close by 2019, and the
