请教一下独立技术移民签证（885）和商业签证（845）的区别

kakamasker

885这个签证的好处大家都是知道的，除了没有选举权基本和公民一样。但是845这个签证从移民局官方网页的说法来看，应该只是一个提供给商务人士的永久居留签证。
下面是这两个签证的移民局原文：
845:What does this visa let me do?With this visa you can:

• work in your established business in Australia
• travel in and out of Australia any number of times as long as your visa is valid
• study in Australia
• have your family accompany you to Australia, who will have the same entitlements as you
• live in Australia as a permanent resident for five years (after 5 years, you will need to apply for a resident return visa).

885:
What does this visa let me do?This visa allows you and any secondary applicants included in your visa application to live as permanent residents in Australia.
Australian permanent residents can:

• live and work in Australia on a permanent basis
• study in Australia at school or university
• receive subsidised healthcare through Medicare and the Pharmaceutical Benefits Scheme (PBS)
• access certain social security payments (subject to waiting periods)
• be eligible for Australian citizenship (subject to the residency eligibility criteria)
• sponsor people for permanent residence.

红字部分就是这两个签证权利的区别，所以我很迷惑有人说的845签证可以转公民的说法。如果真的可以转公民，能不能具体说明下到底怎样才能转公民，能附上移民局的网络链接的话就最好了，这样可以让大家更加了解这个可以解决很多同学难题的签证，谢谢！
