Naisip ko lang, you might still need to take PTE, IELTS or other english exam to prove that you have competent English for skilled independent visa application.
Skilled Independent visa (subclass 189) document checklist
At the time of invitation
You must provide evidence you have at least competent English.
Family members English language ability
For each of your dependent applicants who are aged 18 years or older at the time of application must provide evidence of Functional English.

Magkaiba kasi ang requirement for Competent and Functional English.
This is just a thought lang naman, let's wait for the input of other peps here in the forum specially those that were approved na. Thanks
