"Bulk billing access for person with a valid disability pension card"

I recently sought medical advice after having a very substantial fall in the shower earlier that morning. I landed on my left arm which is very badly bruised and double the size of my right arm. 

I attended a St John Urgent Care in WA to have my arm checked for a fracture.  Mid-morning, I spoke to a Reception staff member. I was advised I needed to see urgent care and there was a fee of $170 minimum. As I understand it, this fee is relatively new (18 months or so). Medicare will rebate about $35.00.

I stated I hold a valid disability pensioner card and asked if that entitled me to bulk billing. I was told no just the Medicare rebate, and not being able to afford the fees was "my problem"

I was not offered any alternatives (i.e. presenting to another location that bulk bills), nor told to go to the ER.

My issues are as follows:

1. Window Signature states that bulk billing is available. If a valid disability pension card is not accepted, what is? I feel it is not clearly indicated that this is only applicable to children either.

2. In my opinion, the incredibly rude staff member was ableist, infantilising, and condescending when I stated I had a valid disability pension card. 

3. Equitable access to health services is a basic human right. The staff member in question did not offer any alternative for urgent medical treatment whatsoever.
