And even including their sposoprship Wests Tigers run at a loss and get a grant from Wests Ashfiled to cover it. They dont run at a profit and I doubt they arnt the only ones.and if you go on their website.
They are listed ( well Holman Barnes ) as a sponsor. So I expect the Bears to have sponsors fund things such as lower grades not the WA government
On top of that west ashfield fund balmains juniors and wests campbelltown fund wests juniors. Wests Tigers dont fund their juniors.
But back to your point, not all clubs run at a profit.
