No, alot of that is due to the fact the NRL has done nothing in Perth so RL has little relationship with the Govt, and in all honesty the WA Govt probably sees that it already has most major sports so doesn't need the NRL. Only help we will get is in the stadium redevelopment but that is more due to the ARU than us. NRL are not a proactive org like other codes have so don't seemingly actively court Govt funding and spend the time building relationships with Govt.
If we ever run out of things to dig out of the ground then we will need to promote WA as a great holiday destination and I can see an NRL team being a great vehicle to do that to the Eastern states, but that may be some time off yet!
