If anyone's having trouble getting a PS5 or Xbox Series X, I would recommend you joining Twitter and following https://twitter.com/AustraliaPs5 and https://twitter.com/AustraliaXSX , also don't forget to turn on notifications. I believe the same person runs both and uses some kind of bots that crawl the websites to see if there's any stock, when it finds some stock it automatically tweets out the place and link to the product.
I managed to get the Xbox Series X tweet on the 20/01/2022 for preorder at EB Games, following that the Ps5 tweet was on the 14/02/2022 and that also was a preorder at EB Games.
Without it I know I would still not have any consoles, so I highly recommend you do it too.
Lastly, get twitter on the phone app so you don't miss the tweet, cause the ps5 was sold out in about 5 to 10 mins when I got mine.
