Didn't state further BOOM. It can end. It's crazy still at the moment, doens't mean it's not going to go flat again for years to come.
What I'm getting at is just because it's a capital doesn't mean it's going to have CG.
You need to do research.
Do further research.
No reason why a regional can't have CG.
Just like a capital city can have stagnated growth.
Sydney is having a boom now, was pretty flat for a long time.
