Good luck, I am in Sydney, and I love it here. I think either city, job hunting is not that easy. Ok naman na you base you decision sa job opportunities. For me lang, hindi straight forward or black and white and job opportunities. Ang suggestion ko, choose a state na you like better since you do have that option. Iba iba kasi personalities ng states dito. Like sydney and brisbane, magka ibang magka iba yung feel nila. If kaya niyo visit niyo both both places, have a feel for it. Check niyo kung saan yung mas feel niyo or yung tumatawag sa inyo then dun kayo sumugal. Good luck, all the best.
