Fortunately at this point in time people who want our approvals are more than willing to welcome us onto their land and their water and up in the air to take a look at the sites they're proposing to put the work on.
The problem arises when we have a complaint about somebody else's work, which may be unlawful, and we need to go to see what they're talking about. We do not have inspection powers whereby we can just come onto the land or onto their waterway in order to access the site to view it. We're forced to stop and to make a formal request—which we normally would like to do anyway, but in some situations it's not possible: there's nobody on the land, and/or it's a remote area.
So the answer to your question is that there's nothing. The word “inspection” isn't even in our legislation.
