An 80-year-old woman who fell and broke her hip — stuck alone on the floor of her home for days — has been rescued by police after a member of Queensland's newly-formed coronavirus Care Army raised the alarm.

Erika Freingruber feared she was going to die alone in her Beaudesert house, south of Brisbane, and believes she blacked out during parts of the ordeal.

Police bodycam footage captured the moment officers kicked down her door after hearing Ms Freingruber calling for help.

"I fell down," she told police officers once they were inside.

Constable Max Gillet and Constable Glenn Engels offered Ms Freingruber apple juice as she was lying on the floor with a pillow under her head.

Ms Freingruber is recovering in hospital after the fall late last month and was visited by her rescuers, who came with flowers in hand.

"Can you imagine a week, nearly a week lying there, without help day and night?

"Every doctor who came here said, 'You don't know how lucky you are that you are alive'.

"If you wouldn't have come, I don't think I'd be sitting here."

Ms Freingruber believes she broke her hip when she stepped out of bed in the morning.

She cannot remember exactly how long she was there but it was up to five days.

"I don't know what happened, I must have fallen unconscious because there's some time I cannot account for."

Constable Engels said welfare checks quite often don't end well and he was relieved to hear Ms Freingruber yell out for help.

He hoped the story of her rescue inspires more people to sign up to be part of the Care Army.

"And hopefully save more lives," he said.
