Using the initiative, hosts can respond to crises in their community by offering housing to displaced neighbours and relief workers deployed to help, the company's website read.

"With Cyclone Debbie we were saying it was phenomenal with 40mm per hour of rain. But this one will have a lot of wind, which is not the case with Debbie.
"We are being vigilant with this system, because it may be not prolonged but it will have a massive impact. We are expecting to see damage."
