Which is why I suggested South Brisbane would be a good halfway option between Ipswich-Logan and South Queensland. One is specific, the other vague.
Plus it would have the advantage of "Brisbane" in its name, which would be good for marketing/sponsorships.
I still think a specific regional name would be best - If Toowoomba is part of the clubs junior catchment it doesn't need representation in the name. It will still be the closest club geographically, and the club would still run clinics and player visits, and offer career pathways.
Plenty of current NRL teams have specific names but are active outside their name region - EG Newcastle streach all the way to Port Macquarie, Gold Coast stretches to Coffs Harbour, Canberra has the whole Riverina, Melbourne all of Victoria, et cetera. Warriors an entire country.
With the mascot, I hope to see something unique, original and relevant to the region. No random animals just for the sake of it. Has to mean something. The Best "Brands" in the NRL are ones that are completely driven by the region it represents -
Parramatta - "where the Eels lay down", Cumberland colours
Easts - c**k crowing in east, french colours from similar mascot
Souths - Red for redfern (waratah), green for local gov, rabbitoh for original players occupation
St George - Red and White Dragons. Red used is that of the Illawarra flame tree.
Penrith - Is the Panther real? Colours are a mess though
Cronulla - Beach -> Surf club colours -> Sharks
Ipswich-Logan Valleys - representing the river valleys of South-Western Queensland, colours including maroon for Queensland plus a couple of more specific ones based on the mascot chosen - light blue and white of a kookaburra would be a good choice.
or something like
South Brisbane Jets (not going to happen but) - Airforce base mascot, chose local colours. Maybe one colour from Ipswich LGA and another from Logan.
I don't know what it will be, but I hope it isn't a completely tacky marketing department name. Like Titans.
