"Accessing proper medical updates about my parent"

My parent has been at RPH (Royal Perth Hospital). They was sent in an ambulance from their nursing home. I was rung up by doctors when my parent was in Emergency and then in the ACU (Acute Care Unit). I was called in to interpret for my parent when they had a CT scan.   I have been to visit my parent a couple of times when they were in ACU and only managed to get a very brief update from nurses, one telling me I would have to wait until she had had her break. Yesterday a nurse suggested that I pop in in the morning and maybe a doctor might be around then.   I live an hours drive from the city and can not just pop in.   I am also trying to keep my sibling living overseas updated.   This morning I received a long account of all the staffing shortages at the hospital and again that I cannot speak to a doctor.   When I got put through to the nurse I was told that my parent - was fine and that when I ring I should ask to be put through to the doctor. I could then hear the nurse being told that no I couldn't ask to speak to the doctor.   Just a few days ago I was discussing a care plan for my parent in case they deteriorated, this was a very distressing call to have.   And now just a couple of days later I feel I am being fobbed off with a  - they're fine?   I plan to visit my parent again soon, but probably by then there will be no doctors around. I am very upset and frustrated that it's so difficult to access some meaningful information about my parent.
