关于temporary visa的medicare levy and surcharge

excite

工作签证，来了不到一年，在E-tax中填了有关选项，觉得有些还是没搞清，上来咨询一下，
因为年收入超过5万，所以我的理解雇主应该是withhold了medicare levy和surcharge了，但是只拿了半年的钱，所以实际年收入不到5万，老婆这期间也无收入，另外每月还要花$400给我和老婆买私人保险，所以我想我应该是可以退回surcharge的。
至于levy，还不是很清楚，看到可以apply a Certificate of Exemption from Medicare Australia，想问问我有资格申请吗，是直接网上申请，还是要填正式表格？
最后，因为来个不满一年，因此Etax里需要手工计算一些天数，有一项应该是days of NO dependents，我和老婆上个财政年度之前就结婚了，按这样应该是366天，但我们在澳洲又不满一年，不知道是不是该按在澳天数计算？
最后，填完medicare后，看了看最后的estimate，发现好像refund多了几百，但是medicare的细目中却什么都没有，如果medicare有refund，应该会有细目吗。
请大家指点，多谢了！！

The first half year you can go the medical office to apply the medical exception certificate and can except the M1 before you come to Australia,

I think your annual income for the time less than sur charge of the M2, I think you are except for the M2, however, if you have the Private Medical Insurance for you and your wife from the date you come to OZ, you can except the M2 as well.
