I have sent you details via the email you sent me over the weekend.
Hearing impaired is one of the NSOD's included in disability bowling, there is a classification component which depends on the result of a hearing test. If you are already a member of deaf sport Australia you have already met that criteria, if not I will have to find out for you as to how we get your official classification done.
If you have any questions please email me again on the address you sent to on Saturday. Again apologies for the delay in responding.
