it's a long read and I don't understand the ins and outs of it BUT if it's saying that EVERY person applying for settlement (spouse, extended family members, etc) need to prove proficiency in the English language - then FANTASTIC! about time something like this was brought in, and I hope other countries follow suit (USA, Australia, NZ, etc).
This is an English speaking country and everyone who want to settle here has to speak engligh. I am of Indian origin but everyone in our family here speaks perfect english (even great grandparents) and that is how it should be if you want to migrate to an English speaking country.
