Im not going to get into the which is best or worst...
Its simple, find a job. Get the name of the suburb and them look for a place near where you work...
Simple...
I work mostlly on the northside and that where my family is at so therefore I live on the northside...
Personally i think Sunshine coast has better waves than the Goldcoast and far more communities to visit. (Noosa, Maroochydore, Coolum, Calundra, Kawana, Pelican Waters)
Tip tho, the city is on the north side of the river, so if you want to work in the city move northside cause as soon as there is an accident or a bridge closure your screwed... So on that basis Northside FTW...
Down side tho is the average flat, town house, house and land are all higher average cost than the southside...
