Congrats on the change Symon. I hope it works out well for you both.
As an ex-Brisbanite, I vote for south side, aka the "Keepin' it real" side
. They keep the latte-sipping X5 drivers north of the river these days. To be honest though, I could quite easily live somewhere bayside, so long as it's near a train line.
Good luck!
