This plant operator job description template is designed to reflect Australian workplace standards and mining industry practices at the time of publication. Confirm the applicable modern award or enterprise agreement for your business and ensure compliance with all relevant work health and safety laws. It does not constitute legal, HR, or professional advice and should not be relied on as a substitute for advice specific to your business, workforce, or circumstances.

About the plant operator role

A processing plant operator (also known as a mineral processing operator or process operator) runs and monitors the fixed plant that turns mined ore into saleable product. Working across crushing, grinding and milling, screening, flotation, thickening and filtration, the operator keeps the process running safely and to target from both the field and the central control room (CCR).

Day to day, operators conduct pre-start inspections, take and log samples, adjust set-points, clear blockages, and isolate and lock out equipment for maintenance, while recording production and downtime. Because processing plants typically run continuous 24/7 operations, the role is worked on rotating day and night shifts, often on a fly-in fly-out (FIFO) basis at remote sites.

In Australia, processing plant operators are usually covered by the Mining Industry Award 2020 (MA000011), which covers metalliferous mining and on-site mineral processing. Plant operators generally sit around Level 2 to Level 4 depending on experience and the range of plant they run competently. Many larger operations instead apply an enterprise agreement. This template provides a foundation for clear, compliant job descriptions, and once hired you can manage rotating crews with mining rostering software.

Key responsibilities

Core duties included in this job description template

Plant operation

Operating and monitoring fixed processing plant — crushers, mills, screens, flotation cells, thickeners and filters — to meet throughput and recovery targets.

Control room monitoring

Watching process variables from the central control room (CCR), adjusting set-points and responding to alarms and trends.

Sampling and quality

Taking process samples, running field tests and logging results to help keep grade and recovery within specification.

Pre-starts and inspections

Conducting pre-start checks, routine field inspections and clearing blockages or spillage to keep the plant running safely.

Isolation and lock-out

Isolating and locking out equipment for maintenance, following permit-to-work and tag-out procedures.

Records and compliance

Recording production, downtime and shift-handover notes, and following work health and safety and environmental procedures.

Skills and attributes

What to look for in candidates

Mechanical aptitude

Practical understanding of process equipment, pumps and conveyors, and the confidence to fault-find and respond to plant issues.

Process monitoring

Ability to interpret control-room readings, trends and alarms and take timely corrective action.

Safety focus

Strong commitment to isolation, permit-to-work and WHS procedures, and to looking after crew mates on site.

Shift readiness

Reliability across rotating day and night shifts, punctual handovers and consistent performance through long swings.

Teamwork

Collaborative attitude on a small shift crew, clear handovers and support for maintenance and other operators.

Fatigue management

Self-awareness and discipline to manage fatigue on continuous 12-hour shifts and remote FIFO rosters.

Qualifications and requirements

The requirements for processing plant operator positions vary with site, commodity and plant complexity. Some are mandatory, while others are preferred or desirable and can be gained on the job.

  • Site inductions (Required)

    Standard site and safety inductions completed before starting on site

  • Working rights (Required)

    Eligibility to work in Australia

  • Working at heights / confined space

    Tickets for working at heights and confined-space entry where the role requires them

  • Certificate II/III in Process Plant Operations

    Certificate II/III in Process Plant Operations, or relevant RII/PMC units of competency, is desirable

  • Pre-employment medical (Required)

    Pass a pre-employment medical and drug and alcohol screen, standard for mine-site roles

  • Previous processing experience

    Prior experience in a mineral processing or heavy-industry plant is advantageous but not essential

Working conditions

Set clear expectations for candidates about the work environment

  • Continuous 12-hour rotating day and night shifts
  • Fly-in fly-out (FIFO) work at remote sites on set roster swings
  • Exposure to dust, noise, vibration and process chemicals
  • Mandatory personal protective equipment (PPE) at all times
  • Physical work including climbing, standing and clearing blockages
  • Strict fatigue management and work health and safety compliance

Award coverage

Understanding the Mining Industry Award

Mining industry award 2020

Most processing plant operator positions are covered by the Mining Industry Award 2020 (MA000011), which applies to metalliferous mining and on-site mineral processing. This modern award sets minimum pay rates, penalty rates, allowances and conditions. View current Mining Award pay rates.

For FY2026/27, adult classifications range from Introductory at $27.53 per hour up to Level 7 at $37.62 per hour, with processing plant operators typically sitting around Level 2 to Level 4. Casual employees receive a 25% loading. Many large mining operations apply an enterprise agreement that lifts pay above the award, so always confirm which instrument covers your site. Use award interpretation software to calculate pay accurately across rotating shifts.

Penalties, loadings and allowances

Continuous processing plants run around the clock, so penalty rates and shift loadings are central to plant operator pay. Under MA000011, overtime and weekend work attract Saturday penalties of 150% for the first three hours and 200% thereafter, Sunday at 200%, and public holidays at 250%. Afternoon and night shifts attract a 15% loading, rising to 30% for permanent night shift, and an underground allowance of $2.06 per hour applies where relevant.

Because rotating 12-hour rosters mix ordinary hours, penalties and overtime, accurate interpretation matters. Model shift costs with the overtime and penalty rate calculator and shift cost calculator before you build the roster.

How to use this template

Tips for customising the job description for your site

1

Add your site details

Include your company name, mine or plant location, commodity and roster type (residential or FIFO).

2

Adjust responsibilities

Add or remove duties based on your plant — crushing, milling, flotation, thickening or filtration — and control-room set-up.

3

Specify tickets

Clarify which tickets and competencies are essential vs desirable, such as working at heights or confined space.

4

Include roster details

Be specific about shift length, roster pattern (for example 2:1 or 8:6) and day/night rotation.

5

Check award coverage

Confirm whether the Mining Industry Award or an enterprise agreement applies and update classification levels accordingly.

6

Review regularly

Update the job description when plant, roster patterns or site requirements change.

FAQ

Frequently asked questions

  • A mineral processing plant operator runs and monitors the fixed plant that turns ore into saleable product — crushing, grinding and milling, screening, flotation, thickening and filtration. Working from the field and the central control room, they conduct pre-starts, take samples, adjust set-points, clear blockages, isolate equipment for maintenance and record production and downtime, usually on continuous 24/7 shifts.

  • Most processing plant operators are covered by the Mining Industry Award 2020 (MA000011), which applies to metalliferous mining and on-site mineral processing. Many larger operations instead apply an enterprise agreement that lifts pay and conditions above the award, so always confirm which instrument covers your site.

  • Under the Mining Industry Award, processing plant operators typically sit around Level 2 to Level 4 depending on experience and the range of plant they can run competently. New starters begin lower and progress as they take on more equipment and control-room responsibility. See our Mining Award pay rates guide for current rates at each level.

  • A plant operator runs and monitors the process, keeping the plant producing to target and responding to alarms and blockages. A maintenance tradesperson (fitter, boilermaker or electrician) repairs and services the equipment. Operators isolate and lock out plant so maintenance can work safely, then return it to service — the two roles work closely together on shift.
