Yes although regarding Brisbane, they have a lot of expat Victorians who’ve moved up over the years to thaw out from years in bleak city. So think the lions have plenty of barnacles stuck to their hull, plugging the gaps to keep the old boat afloat.
But on the subject of Qld Rugby - what ever happened to Ballymore??
Ballymore is still there. They decided to move away from their spiritual home to Suncorp when it was re-built. They forgot one thing though. Unless they have a championship winning team playing an entertaining brand of Union.... which has only happened once in their history, they aren't popular enough to warrant playing there permanently.
Re: the Lions, I see what you mean. They do survive on away support from ex-pats for sure.
A second NRL side here would be bad news for both the Lions and Reds more than it would be bad for the Broncos.
