"Through clever innovation, Westpac Little Ripper Lifesaver can help stop the spread of COVID-19. Our fleet of specialised drones will be able to spray environmentally-friendly disinfectant to ensure public spaces remain safe," the bank tweeted on Thursday.
"Help when it matters."
In its video, the bank said the drones could be used to spray schools, universities, child care centres, aged-care facilities, hospitals, and supermarkets.
Westpac also said the speakers in its drones could be used to make public announcements.
Nothing says 2020 more than being sprayed with chemicals from a corporate-branded drone, while simultaneously being harassed by a disembodied voice.
In less insane responses to COVID-19, the bank finally embraced Apple Pay earlier this week.
"We have seen a significant increase in customers using digital banking in recent weeks as more Australians stay at home," Westpac Group chief executive of consumer David Lindberg said on Tuesday.
Westpac was previously part of the banking group that lost a legal fight against Apple to try to gain access to iPhone NFC technology to implement their own payment solutions, rather than use Apple Pay.
