Change in points marks

I just got an email from my agent as follows :

Dear Client,

This email is to notify you that department of Home Affairs has made changes in points test pass mark for subclass 489, 189 and 190 visas. The point tests mark will increase to 65 points from 1st July 2018. Therefore the applications that had 60 points for 189 will be invalid from now.

Also please note that the ACT 190 nomination program remains closed for overseas applicants until further notice

Is this true and how it will affect us
