Is the property growth in Brisbane a bubble?

It's clear that Brisbane has been close to the top in terms of property price growth around Australia. Obviously, the upcoming Brisbane Olympics is a major factor for this.

Would prices have risen (this much) even without the Olympics? How sustainable is this growth?

What do you think will happen to prices just before, during, and after the Olympics?

Will prices go through a mild self correction phase, continue strong growth, or crash all together?
