Under the scheme, government officials are matching older people confined to home with volunteers who'll help them with tasks such as food shopping and pharmacy supplies.

"If we can keep our seniors safe, we can prevent them from ending up in hospital or in ICU and potentially save lives," the Queensland premier said.
