Sorry to hear the situation . I live in a US state where many people have two drive over 5 hours for basic healthcare. I'm in a city of about 1 million which I would much rather live out on a farm like I used to but I can no longer .
Are there any asthma doctors? Or even a primary care can prescribe some things. A drug called Qvar significantly helps my symptoms generic is Beclomethasone . It is an inhaled steroid so not much leaves your lungs. While too many pulmonologist focus on sleep medicine if you can use the internet to try to find one the treats pulmonary fibrosis ( which is the scaring that creates ILD) that might help. There are several causes of ILD, so idk if you have had exposure to silica dust, asbestos , mold, etc? Another prevalent cause is autoimmune diseases. Try to get your primary to run an autoimmune panel becasue getting to a rheumatologist will help get you to a pulmonologist. There should be a national association of pulmonologist for AU that maybe a resource for finding the right doctor. There are several new medications for ILD which is why I think you should do what ever it takes to get to that ILD clinic. Melbourne is pretty big I would try calling the University hospitals and the larger hospital and asking for the pulmany department then asking who ever answers if they treat pulmonary fibrosis or ILD. A lot of hospitals don't just post online these things. I called the 3 big hospitals in Minneapolis after not seeing anything on their web sight and found out 2 have ILD clinics.
