GREP help "apply style before the ' – ' and add return"

Question

Hi,
I'm a newbie to GREP and not good at code so I need some help.
I think if I new the code to say " apply Heading Paragraph style to text before the ' – ' and add return.
Then it would work.
I'm OK with looping nested paragraph styles.
This is what I have currently got:

Ozcare Allied Health Program – 5569 6200 / Fax [phone] 
Physiotherapy, occupational therapy, speech pathology, podiatry, dietetics and social work.

And this is how I need it formatted with styles applied

Answer 1

Thanks for the help so far. It's working but I still to iron some things out.
Replacing the em dash with a paragraph space or return is straight forward. But getting the styles applied while doing that is not working.
Also I want to split the phone and fax separated by the '/" onto separate lines.
