Do Australian schools require PhD students to obtain a master's degree before making an offer? Do they not even give a conditional offer?

That’s right. Scholarships from many Australian universities depend on whether you have obtained CSC. PhD application. There is no con-offer, but a firm offer directly. In addition, you should remember that you can go there at any time as long as you and your instructor have negotiated the start of the PHD semester. My suggestions and practical arrangements for you are as follows:

In June 2014, IELTS will meet the language requirements for direct entry and cannot be matched with language courses. Start applying for CSC from September to October 2014. At the same time, you start to prepare to find a mentor to see which mentor is willing to accept you and you want some research topics. After obtaining CSC, you can directly apply for Australian scholarships, but there are also some universities that can directly provide scholarships.

My students from Peking University graduated in November and June and entered the University of Melbourne to study for a PhD in December and September. Moreover, Australian doctoral applications are based on your undergraduate results, not your master's degree. The master's degree is only the most reference.
