The NRL aren't choosing a team solely on 'how much money they make from football operations", namely because said money is the clubs and not the NRLs but also because the club grant covers the expense of running a team fully.
The bolded part of your claim is complete bullshit.
On p27 of the 2020 Gemba report on NRL expansion, commissioned by about a dozen clubs, said the smaller teams require about $23.6m per annum to cover the costs of fielding a team in the NRL. The club grant is no where near $23.6m. Clubs need to generate around $10m of their own revenue to cover the basic costs.
On p28 it says the NRL grant only covered $13.6m.
The grant has increased since then, but not by much. Clubs still need to generate $8m or more from football operations just to compete with the smallest Sydney clubs, such as Wests Tigers, Cronulla Sharks and Canterbury Bulldogs. These clubs make around $10m from football operations most seasons, but some times they fall short and have to rely on a handout from their Leagues Club to cover the shortfall.
A Perth-based team will need to generate $8m+ from football operations because they will not have access to gaming revenue. If they want to be successful like the Storm then they will need to generate significantly more. So yeah, you can bet your arse that the ARLC will want to know how much revenue a Perth-based team will generate from football operations and its owners. The Dolphins were brought in because "the business case stacked up". They provided about $30m+ deposit to ensure the ARLC doesn't have to step in should things go awry. A Perth-based team will not have reserves like this sitting by.
It's also rich to "boast" about the Tigers ability to generate revenue from football alone, when they have generated nothing but money from pokies for the last 3 decades.
Sigh.
I'm talking about the amount they will generate from football operations when they're admitted into the NRL. The club will generate a good sum from sponsorship and corporate hospitality because they're based in a central location and will play all of their games out of Lang Park.
Also the use of Lang Park, is nothing unique to the Tigers.
Sigh.
The corporate facilities at Lang Park shit all over every other stadium in the country. The general admission seats are also the best in the NRL. The advantage of playing out of Lang Park will provide them with more revenue from game day than a team playing out of a suburban dump.
