How to structure it

Opening

Name the role and, in one line, the strongest reason you're a fit. Skip the throat-clearing.

Middle

One or two paragraphs of real, specific evidence: what you did, and the result. This is where most letters go generic. Yours shouldn't.

Why this employer

One genuine, specific reason you want this job at this company, not any company. Vague enthusiasm reads as a template that wasn't customised.

Close

Thank them, note your resume is attached, and make it easy to reach you.

Re: Application for Plumber's Assistant

I am applying for the Plumber's Assistant role with [Company Name]. After supporting licensed plumbers on residential renovations and maintenance callouts, I know what keeps a job moving: prep done early, tools and fittings where they are needed, and a site that stays safe and tidy from start to finish.

The work I am proudest of was a two-bathroom re-plumb where I handled the measuring and cutting for the copper and PVC runs and kept fittings sorted by stage as the rough-in progressed. Because everything was staged and checked against the plans before the plumber picked it up, we finished the rough-in comfortably ahead of the inspection and the only rework was one length we caught ourselves before it was fixed in place.

What draws me to [Company Name] is [add one genuine, specific reason: a project, value, or market position you can point to]. I want to keep building my skills under plumbers who take that approach, and I am ready to commit to a Certificate III apprenticeship with the right employer.

Thank you for considering my application. My resume is attached and covers my tools experience, safety record and availability, and I would welcome the chance to talk through how I can help your team.

Getting it right

This is a starting point, not a guarantee of interviews. Make it specific to the actual employer before you send it.
