..."The revised start date for the changes would be from 1 July 2018 if the government can seal a deal to get them through parliament."
..."SBS News understands all applications received until then will be processed under the existing law."...
So....changes are inevitable....it's just a matter of time and negotiation but I would bet there will be some sort of English language testing, PR for more than 12 months etc. Importantly I hope the move to grab more power is cut short irrespective of future negotiations.
