I've seen a few articles about this and supposedly it's from Australia. Allianz and NRMA supposedly, I haven't checked but if you get a quote from those companies you can check it yourself.

There's an insurance industry article I saw which makes me think it's legit because it referenced "adjusting pricing" which means it's a new option which will be adjusted based on claims of this group. So it'll end up somewhere between Male and Female rates.

So yes, cheaper rates for Men.
