I am currently living in Toowoomba moved from Gold Coast. I do prefer living on the gold coast, but I guess Toowoomba is not so bad. Actually, the weather is much batter than the gold coast. Also, one of my co-worker who is used to live in Brisbane and has 2 kids likes living in Toowoomba due to its children's education aspect. But I know someone who has left Toowoomba, because she couldn't find a decent job. For me, I would live in a northern part of the gold coast and travel to work in Logan since it's quite close.
Hope it helps!
