Mineral Resources (Sustainable Development) Act 1990

An inspector who enters a place under this Division may take (without payment) samples of any thing at the place that may be required for analysis.

If an inspector intends to take a sample, he or she must notify the occupier or apparent occupier for the time being of the place of his or her intention.

Unless it is unsafe to do so, after taking the sample the inspector must—

divide it into as many parts as are necessary and mark and seal or fasten up each part in a way that the nature of the sample allows; and

if the occupier or apparent occupier requires the inspector to give them a part, give one part to that person; and

keep one part for future comparison.

If it is determined that the sample is to be analysed the inspector must submit another part to an analyst for that purpose.
