Urban pigeon shooting question

[elnino]

Hi all, I'm in SA and I have been approached by a business (friend of a friend style) that is on a large gated property but still in an urban area to help out with pigeon control.

I have all the kit to do the job, suitable license, hunting permit, insurance etc but I have never done this sort of thing in an urban area and I am not a commercial operator (no pest control licence etc). In all likelihood I could get the job done with no chance of interaction with the public and it'd be generally performed at night anyway but is there anything legal I need to cover off? Like let the police know beforehand just in case there is a call/complaint/report? Will they even allow it if I'm not a commercial operator? Would any part be considered illegal (SA does have some weird laws)?

Obviously it would all be performed with safety as a top priority, ensuring backstops etc and only with PCP rifle.

Or am I just getting into too much of a grey area and best to just stay the hell away?
