Step inside: We’re supporting Sustainable House Day 2026

No sales pitch. No showroom gloss.

Just a real person and a real home, with all the practical detail you want.

That’s Sustainable House Day.

“On Sustainable House Day, real people open real homes across Australia.

"Step inside architect-designed sustainable builds, clever retrofits, all-electric upgrades, efficient apartments and climate-resilient rebuilds.”
— Kate Walsh, Renew

According to Renew, 70% of past attendees report planning to make changes to their own home within six months of attending an open home.

About Sustainable House Day

Sustainable House Day is coordinated by Renew, a membership nonprofit that has been working to help Australians improve their homes for climate and energy resilience since 1980.

Renew also publishes Renew and Sanctuary magazines, two of the most useful resources for anyone thinking about sustainable living or building.

This year, Bank Australia is proud to be principal partner of Sustainable House Day.

The open homes on 17 May are just the start.

Online Learning Month runs from 18 May to 17 June, with expert-led sessions on electrification, passive design, retrofit pathways and energy efficiency.

Homeowner Q&As run alongside, so you can continue the conversation with the people whose homes you’ve visited, right through to implementation.

One ticket, two ways to learn

A ticket to Sustainable House Day costs $15 and gets you into as many open homes as you can fit into 17 May - plus access to Online Learning Month, with expert-led webinars and homeowner Q&As running from 18 May to 17 June.

What’s in it for customers

If you’re already a Bank Australia customer, you have free access to the Electrify Your Home tool through the Bank Australia app.

It helps you understand which changes to your home would make the biggest difference to your energy use and running costs, at a pace that suits you.

If you’re not yet a customer, you can open a transaction account today, or our Clean Energy Home Loan is designed for people buying or building energy-efficient electric homes.

It’s one of the ways we put our lending to work in support of the homes Australia needs more of.
