(1) The Inspector - General has, in connection with:
(a) the performance of the Inspector - General's functions and duties under this Part; and
(b) the exercise of the Inspector - General's powers under this Part;
such powers in a Basin State that is a referring State, or in the Australian Capital Territory, as the Inspector - General has in connection with the performance of the Inspector - General's other functions under this Act.
(2) The application of subsection (1) to the Inspector - General's powers under Part 10AA in relation to premises in, or information held in, a referring State or the Australian Capital Territory is not limited by subsection 223(1) or 238(1).
(3) Part 10AA applies as if:

(b) a reference in Subdivision B of Division 1 and Division 3 of that Part to a designated compliance provision included a reference to a provision of this Part or regulations made for the purposes of this Part.

(b) exercise any of the powers under that Subdivision;
except:

(i) determining whether a provision of this Part or regulations made for the purposes of this Part has been, or is being, complied with;
(ii) determining whether information given in compliance, or purported compliance, with section 222D, in its application under section 86J, is correct;
(iii) determining whether information given in compliance, or purported compliance, with section 238, as applied by this section, is correct; or

(5) Also, the Inspector - General must not require a person to give information under Division 3 of Part 10AA as applied by this section unless the Inspector - General has reason to believe that information relating to a matter that is relevant to the performance of the Inspector - General's functions or duties, or the exercise of the Inspector - General's powers, under this Part is in the person's possession, custody or control (whether held electronically or in any other form).
