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.

Thank them, note your resume is attached, and make it easy to reach you.
Re: Application for Plastics Machine Operator
I am applying for the Plastics Machine Operator role at [Company Name]. I have run injection moulding and extrusion equipment in polymer manufacturing, and I am used to setting up tooling, holding parameters to spec and catching defects before they turn into scrap.
One night shift, the parts coming off my machine started showing short shots and heavier flash than the approved sample. I worked through the likely causes in order: checked the dryer and material condition, reviewed shot size and hold pressure, and traced the fault to a worn check ring that was letting material slip past the screw. I isolated the machine, moved the run to a spare press so the order kept moving, and set the spare up to the approved parameters. Maintenance replaced the check ring and I had the original machine running again later in the shift, with no non-conforming parts leaving the area.
I want to work for [Company Name] because [add one genuine, specific reason: a project, value, or market position you can point to]. I am looking for a plant where operators are expected to understand the process, not just press a button, and where the setup sheets and quality standards are taken seriously.
Thank you for considering my application. My resume is attached and covers my machine setup, inspection and maintenance experience in more detail. I am available for rotating shift work and can complete a pre-employment medical and site induction at short notice.
Getting it right
- Keep it to one page. A hiring manager spends seconds on this before deciding whether to read your resume.
- Address a named person where you can find one, rather than "To Whom It May Concern".
- Don't repeat your resume line for line. Use the letter to add context a bullet point can't: why this role, why now, why here.
- Match the tone of the job ad. A formal listing calls for a formal letter; a casual one gives you room to write more like yourself.
This is a starting point, not a guarantee of interviews. Make it specific to the actual employer before you send it.

- How long should a cover letter beA cover letter should usually fit on one page. That's the standard in Australian government careers guidance.
- Do you still need a cover letter in 2026?Most advice online says skip the cover letter unless the ad asks for one. Australian government careers guidance says include one by default. This explains where the two positions differ and how to keep yours readable by an automated screen.
