Do I need to apply for a study visa or will it be ok for me to apply for a L type?

I have an Australian passport. I wish to travel to Bejing in early June to do a 4 week Chinese language course for my personal development. After finishing the course in early July I will travel to Shanghai to undertake a two week study at Fudan University (officially organised with a Melbourne University). Are all L types issued for at least 3 months? Thank you for your help. KR
