刚才去悉尼大学搜了一下,跟commerce相关的有好多，下面三个应该是你提到的：
1.master of commerce
Specialist in focus while covering a broad range of study, this degree develops the advanced skills and knowledge required for a high-level position in industry, commerce and government. Career opportunities include positions in accounting, marketing or other specialist fields, as well as roles in a variety of business fields
The Master of Commerce gives students the advanced skills and knowledge required for high-level positions in industry or government. Students can specialise in one or two areas of study to fast-track their current career or change their field of expertise entirely. The core units of study provide the foundation for diverse areas within the commerce field.
The Master of Commerce can be awarded with Honours to students who are looking for much greater depth in their major area of study.
2 master of international business and master of commerce
This program combines the Master of International Business with the Master of Commerce. The two master’s degrees can be awarded in a shorter time than it would take to study them independently.
3.master of commerce and master of logistics management
This program combines the Master of Commerce degree with the Master of Logistics Management. The two master’s degrees can be awarded in a shorter time than it would take to study them independently.
看起来是后两个比较划算，除了commerce还可以学点别的东西。怎么选择还是看你自己以后想干什么。
祝顺利
