When I was changing services in the Aussie military I had to do all the initial medicals again, and my hearing was an issue.
Coincidentally, I had had a shotgun let off near my right ear when I was younger, and my audiogram wasn't too far off yours, although I didn't have the 30 db or so for the lower frequencies.
They sent me off to a specialist who did some more audio testing, checked things like my tympanic membrane mobility and eustachian tube function, and also did a speech intelligibility test which consisted of listening to a bunch of recorded words and saying what I thought they were.
Anyhow, he gave me a pass and I was right to go. For subsequent military medicals I would take a copy of his report so that if any of the medics questioned things I could show them that it had already been dealt with.
I'm sure it will be a good idea to see the specialist.
Now I've left the services and am doing standard civil Aussie Class 1 medicals, the testing seems to be quite a bit less stringent. I did an audiogram on my first one, and nothing was said; the last couple the doc seems to have just been talking to me normally and figuring that's a good enough test.
