Compare money that goes towards women's only shelters, organizations and charities. With money spend on those "sheds". Even dog shelters have better funding!
But the point of the men-only ones is to allow men to socialize with other men and talk about problems that affect them only or problems they don't feel comfortable talking about in a mixed setting.
It's not sexist to want men only spaces, just like women only gyms and salons are not sexist.
I dunno, maybe ask the woman you quoted:
"While the local men's shed welcomes women, Ms Reardon said there were many women who wanted their own space.
"People like me that would feel intimidated going into what would traditionally be a man's space … want to learn with other women," she said."
The women themselves don't want to be around men because men are so horrible apparently.
Also, each sex tends to have a bit of a difference preference on how a meeting-space should be. For example: Most of my male friends tend to hang out in garages/sheds some of the time. Never seen a woman choosing a those locations.
But not so long ago, I saw an article about women trying to open a similar shed but finding there was a funding program which was specifically only able to men's sheds. I'm surprised they can get away with it.

It gets stranger and stranger.
