Joint tenants -> aged care means testing?

Hi there,
My parents and I own and live in a property altogether as joint tenants. My query is: what happens if they need to go in to aged care? Will the property need to be sold in order to pay for the RAD? Or because I have an interest in the property, I will be considered a “protected person”?

For reference, it has been less than five years and I do not receive an income support payment, however, I would be eligible for one if needed.

Thanks
