You are on the right track. Keep doing what you are doing and remember that you are making a move because you are seeking a better lifestyle. At times it will be difficult as you will leave behind not only loved ones but your hometown and many things that you are used to. Adelaide is not that different from other places I've been to but the job market is tough down here. Don't let this dismay you. A newly arrived couple have already secured jobs (maybe not what they expected but good jobs anyways) by being proactive and going out there and meeting people. If you really want it you can get it, maybe it will turn out better than you expected and maybe not. One thing is for sure though, if you are willing then you will get employed.
Personally, I didn't get anything in marketing but I've been working ever since I got here. Now I'm really looking forward to starting a new career in security. I have good protective instincts, am generally good with people of diverse backgrounds, smart enough and fit enough and already people in the industry are giving me their cards. I decided to go for it because I have it in me. It's not going to be marketing but hey it pays well.
On the other hand I am starting an online import/export/digital marketing/digital sales sort of business. It will serve as my side business until it proves worthwhile then I might switch and continue doing it on a full time basis.
Remember that we as grownups have the tools to success. We are risk takers as we have left behind the comfort of our own countries and are almost starting from scratch in a new arena. We can make this work if we want to. If for some reason we don't quite make it in Adelaide we can always move interstate.
