Recommendations training around Brisbane/Noosa

To you Australia-experienced people: I am in Melbourne for business travel in July and thought to stick around for 1-2 weeks for some cycling/tri training and experiencing the Aussie lifestyle.

As it is winter I thought it may be better to travel north for better weather. I heard of Brisbane or Noosa as spots.

Does that sound like a reasonable plan? Are there any other hotspots that I’m missing?

Thanks!
