Before granting consent for development that is likely to have an impact on a place of Aboriginal heritage significance, or that will be carried out on an archaeological site of an Aboriginal object that has Aboriginal heritage significance, the consent authority must--
(a) consider the effect on the heritage significance of the place or site and any Aboriginal object known or reasonably likely to be located at the place or site, and
(b) except where the proposed development is integrated development, notify the local Aboriginal communities (in such way as it thinks appropriate) of its intention to do so and take into consideration any comments received in response within 21 days after the relevant notice is sent.
