Telecom/ Spark Wi-Fi and SSL

I've discovered something dodgy going on with Spark's WiFi hot sopts.

Edit: Apparently it's the Authentication kicking in. But they shouldn't have to use a fake SSL cert. There must be a better way.

While connected to Telecom (aka. Spark) Wi-Fi, I get these alerts pop up on my iPhone...

When I click on Details, it tells me that the WiFi access point is masquerading as Google. That is not good.

So I click on More Details ...

Come on Telecom, I mean Spark, stop intercepting and snooping my Google traffic.

I have to turn Wi-Fi off now when I'm away from home.
