175&176申请需要提供什么纸质材料？

chencius

从1119表上看到需要提供的材料如下：

Skilled – Independent (subclass 175)
To be eligible for this visa you must:
• satisfy the basic requirements (see page 7); --->就是自评的东东，略过
• be able to pass the points test; --->同上
• at the time you apply, you must submit evidence that:
– you are under 45 years of age; --->这是指出生公证对吗？
– you have been employed in a skilled occupation for at least 12 of the last
24 months OR you met the Australian study requirement in the last 6 months; ---> 这里指什么材料？推荐信，收入证明，工作经历公证，合同公证，税单，社保, CV??
– the relevant assessing authority has assessed your skills as suitable for working in
your nominated occupation (if the assessment is based on an Australian
qualification obtained on a student visa it must have been part of a CRICOS
registered course); and --->职业认证的证明？
– you have ‘competent’ English. --->雅思成绩？

要加社区分的话，清华认证也要加进去对吧？然后无刑和体检是补料的时候再做对吗？
相比175，申请176就只多一个州担保的证明就行了是吧？纸签和电签提供的材料一样吗？

新手上路，问题比较多，请多包涵。
