WA Premier Mark McGowan is right, page-102

I do see the original article that references the 59% here:
https://www.science.org/news/2021/08/grim-warning-israel-vaccination-blunts-does-not-defeat-delta

(is does also mention of that 59% fully vaccinated, 87% were 60 or older)

That was posted on August 16th. Perhaps since a month has past more data has come through. I would always assume the most recent data is more accurate - but it's interesting to read none the less and I see what you're saying was clearly written at the time of that article.
