More Australians are upgrading the tech in their homes to not just to keep the lights on but make sure they stay connected during natural disasters.

From solar panels and batteries to electric cars and better broadband, experts say at-risk households can take action to avoid being cut off for days at a time.

Disaster-proofing upgrades were high on Jenny Bailey’s to-do list when she moved to Porepunkah, in northeast Victoria, two years ago.

“It’s a regional area, it’s bushfire-prone, it’s flood-prone, so it’s nice to feel a little more resilient,” she said.

“If we get serious bushfires here, the power could be out for days.”
