My local store Geraldton WA had a few, other stores might have some too?
It didn't have a tag next to them so I went and scanned at the price checker and it showed up as $0.20, so I picked one up for my friend too.
Same item as this deal, https://www.ozbargain.com.au/node/688415
Can't find this item on their website so I'm guessing its just clearing stock, you may need to call your local store to check first.
If you dont have a PS5, then its a really cheap 95cm USB C cable
yeah this comes with a type c cable that is well well worth 20c!
