Write a referral letter to a client's GP.

GP name (or 'GP' if unknown): {{gp_name}}
GP practice: {{practice}}
Client first name + surname (or initials): {{client_name}}
Client DOB: {{dob}}
My discipline: Physio
Reason for the letter (e.g. requesting imaging, requesting referral elsewhere, providing update on treatment, escalating a finding): Providing update on treatment
Clinical context (your raw notes — what you've done, what you've found, what you're concerned about): {{context}}
What I'm asking the GP to do: {{ask}}

Write a formal medical letter, 250-350 words. Standard structure:
- Opening: 'Dear [GP], Re: [Client name], DOB [date]'
- Brief context (1 paragraph): who I am, when I started seeing the client, what for
- Clinical findings (1-2 paragraphs): what's happened since referral / start of episode of care, key findings
- The ask (1 paragraph): clear, specific request
- Closing: 'Please don't hesitate to contact me to discuss. Yours sincerely.' + my name placeholder + AHPRA registration placeholder

Use formal medical English. No jargon-for-jargon's-sake but accurate clinical terminology where appropriate. Australian conventions (DOB format dd/mm/yyyy).

Return the full letter.
