The Contaminated Sites Act 2003 requires the owner of a contaminated site or anyone who knows or suspects that they have caused a contamination to be reported immediately to the Department of Water and Environmental Regulation (DWER) on 1300 762 982.
A fine of up to $250,000 may apply for failure to do so, with daily penalties of up to $50,000.
Properties classified as contaminated may be required to undergo remediation to address the issue or may have restrictions placed upon it. Restrictions may be in the form of limiting activities or the type of use permitted, for example prohibiting extraction of ground water or restricting property to industrial use and prohibiting more sensitive uses such as residential.
