That is not a colonoscopy. That is a stool sample and as other replies noted this gets sent out every two years to every one. In the UK from age 60 Australia seems to be from 50.
If that tests positive then you get a colonoscopy to check more things.
If you have had colon cancer then you get a full colonscopy evry two years and an MRI every year.
