Motorcycle Insurance Claim Issues

My son and I went for a ride on the weekend My son riding his motorcycle slipped on the road and consequently knocked me off my motorcycle

He has comprehensive motorcycle insurance and I’m uninsured His insurance company is claiming that because we live under the same roof, they won’t pay for the repairs to my bike We individually own each bike There are two registrations and there is no cross ownership on either bike In a police report, my son was held responsible for the motorbike accident

Do I have a case against my son's insurer? Go to https://wwwLawAnswerscomau/, Australia’s #1 Legal Aid and Legal Questions Site, like I did, to learn more
