This article gives us a better idea, couple of quotes.
"The Dolphins intend to play most of their games out of Suncorp Stadium with the new stadium to host a couple of games a year and to serve as the main training field for the NRL side"
- 9 @ Suncorp, 2 Dolphin Oval, 1 Sunshine coast potentially.
"One of the most attractive things about the Dolphins being the next Brisbane-based NRL team is that they already have in place and own what most expansion teams go bankrupt trying to achieve. The infrastructure is already here,"
- Valid point
"The bid will also engage with fans about the name to precede 'Dolphins', although the bid team has determined that it won't be Redcliffe in order to broaden its appeal in the south-east of Queensland"
- Moreton Bay Dolphins, North Brisbane Dolphins etc... Taking right steps here IMO.
"Another frequently-asked question is whether our colours will be the same as the Redcliffe Dolphins. Red and white is non-negotiable, that is the Dolphins' colours, but when you think about getting the public involved we will ask them what other colour they would like to see added to that."
- Personally would go for a grey/silver as the third colour.
