I can tell you now there is no such thing as a fallback option..... gold coast titans is living proof of that, along with manly and cronulla still being present, no one is going anywhere.
there's the dumbarse codes like ARU who folded the rebels recently and force pre covid etc and ALeague who created clubs in Townsville, Gold Coast wherever just to watch them implode after a few seasons, unlike those codes NRL will prop up and keep their clubs relevant for the long run, they've done it for multiple clubs over the past 20 years, they'll never turn their back on any of thier brands, not now, not ever
