YRED is a great spot to fly out of and has reasonably low density traffic. But as mentioned space is the issue with all the spots around Brissie. You could probably get something at Archerfield but that is may be because everyone else is being priced out and leaving
The advantages to YRED (similar for YACB) is it is on the coast, so easy to get to the islands or up the coast, and not in the middle of the city/burbs like Archerfield.
