@hopeful_Z if I'm in your case, I'll grab it because you have the privilage of invitation where others here are waiting for so long to get their invites. If you wait for 189 visa then circumstances changed and you were not invited, you might regret of not selecting the prior choice. By the time you are in Australia, it is still a PR visa even there is a restriction of movement with other states and our main goal is to enter Australia as quick as possible as their government right now has pressure to cut migration intake anytime and the more you take longer to have an invitation, the more it makes it difficult later on as minimum points will be higher and more requirements will be imposed in each states. End of the day, it is your choice. This is my simple advice. Let's wait for others opinion.
