That's the issue with these custom ADSB solutions that pilots are using.
FR24 for example hides the rego of the VicPol helicopters, but not the aircraft itself. As DF says ADSB exchange hides SAPOL...
So who knows what information you're getting on your iPad and it's reliability? These solutions are realistically for non-pilots who want to know what's flying over their house, they aren't suitable for pilots.
Investment in ADSB is the only way forward in terms of reliable safety with coverage at all levels, that doesn't depend on a 4G connection, uncertified receivers at someone's house, their internet connection and some website hosted on the other side of the world, plus the latency that goes with it through some choked up internet pipe between Asia and Australia.
