REFERRAL LETTER — ENDOCRINOLOGY

To: Endocrinology Department, Westmead Hospital
Re: [Patient name] · DOB [redacted] · Medicare [redacted]
Date: 31 May 2026

Dear Dr [Name],

I am referring this 54-year-old gentleman with a 6-year history of Type 2 diabetes mellitus for specialist review. He presents with suboptimal glycaemic control:

  • HbA1c: 9.2% — above target, worsening over 12 months
  • BMI: 34 — Class I obesity contributing to insulin resistance
  • Current regimen: Metformin 1g BD, Empagliflozin 10mg
  • BP: 138/86 · eGFR 72 · no proteinuria

I would appreciate your assessment regarding intensification of therapy, including the suitability of GLP-1 receptor agonist or insulin initiation.

Yours sincerely, Dr S. Chen MBBS FRACGP

Review this outgoings clause from a retail lease — "The tenant shall pay all outgoings including council rates, water, building insurance, external façade maintenance and any levies imposed by the owners corporation." Tenant is a café, 5-year lease, Surry Hills. Flag risks.
Outgoings clause — risk assessment

⚠ High risk — 4 material concerns:

  • External façade maintenance: Non-standard for retail leases. Typically a landlord obligation under s.52 Retail Leases Act 1994 (NSW). This clause attempts to shift that obligation — likely unenforceable but creates dispute risk.
  • No outgoings cap: No limitation on year-on-year increases. Negotiate a 5% annual cap or CPI-linked ceiling. Industry standard for NSW retail leases.
  • Building insurance scope undefined: "Building insurance" should be limited to the structure — not contents, public liability or loss of rent (landlord's risk). Clarify with express carve-outs.
  • Owners corporation levies: Special levies (e.g. capital works) could be substantial and unpredictable. Exclude or cap at ordinary recurrent levies only.

Recommended redraft: "The tenant shall pay outgoings limited to council rates, water usage and building structure insurance, capped at a 5% annual increase, excluding capital works levies, extraordinary assessments and maintenance of the building exterior."
