Drones in Australia

I'm a bit addicted to these "range test" videos. The pictures are great. But I think they're of little use for anything given we are required to keep our drones in line of sight. What is a reasonable line of sight range for a Mavic Mini? I struggle to keep sight of mine at 200 metres. Is a strobe a valuable addition to extend the LOS to keep within the rules? Anyone done any research on this.
