Got this from another forum:
An update from Immigration SA can be found here.
The key points are:
The last date that 489 visa applications can be submitted is 11am on 14 August 2019
Immigration SA will try to process all 489 visa applications by the deadline of 10 September 2019
If a decision has not been made on your subclass 489 state nomination application by 10 September then Immigration SA will contact you after this date
190 visa applications will most likely be processed after 10 September so don't expect an invitation until October at the earliest
