They've certainly found in New South Wales that it's a worthwhile health investment by putting a small amount of money into

investing in the functionality of people's houses saves them a lot of money down the track in services.

Yeah, look, certainly when we began this work 40 years ago, the prevalence and impacts of extreme heat on health isn't what it is today.

And it's certainly not what it's projected to be in 30 years from now.

There's nothing like living for a month in temperatures above 45 degrees to really sharpen your focus.

So what's becoming crystal clear is that houses being built today throughout much of remote Australia will be uninhabitable within their 30-year lifespan.

So that's certainly the next big challenge.

You know, we need to get serious about making houses cooler in summer and also warmer in winter.

Sadly, yeah.

Look, I think you need to work with both.

You need to work with passive improvements, but passive improvements alone are absolutely not going to be enough.

We are absolutely going to need to air condition housing.

And along with that comes the energy security to power those systems.
