I only did a project during this exchange, so I cannot say anything about the courses at Griffith. If you will be doing a project I have some suggestions that I think you should pay close attention to.
First of all, start researching what groups you are interested in joining well in advance of deciding where to go. Try to primarily choose a group, and let that dictate your choice of university, rather than the other way around.
If you get a response from one group, don't settle with it too soon. Rather, contact several groups and keep your options open. I want to particularly stress the importance of having a supervisor that you get along with well and is interested in your project personally. Now, this may seem difficult when you have not met face to face, but try to see if you can schedule a skype-conversation with both the PI and your daily supervisor, for example by
In regards to the choice of group, I would suggest factoring in the research-methods into your decision. Ideally, you want to learn a technique that is on the rise and will be used more in the future. Of course, it should be a fun one as well. Try tomake sure you have a detailed plan for the project before you go.
As for biomedical research in Australia, get used to inductions. For me it took about two weeks before I was allowed to perform all the laboratory methods I was expected to do hands on. I recommend two things relating to this. First of all, try to speed up the process as much as possible, even if it means that you will be nagging on them a bit. Remember that you ideally will only spend one semester with this project. Try also to use this period for doing other things related to the project. For example, I setup the structure of my thesis, my referencing system (zotero), and wrote most of my background during this period. This will prepare you for the practicalities of your project as well.
Another thing is to not be afraid to ask for help if a method is not working or you are having trouble with it. Although you may want to seem independent, you are not expected to be. Use this opportunity to learn good laboratory practice.
