Controls and PLC Engineer Salary Guide Australia 2026

Controls and PLC Engineer Market Overview

Controls and PLC engineers are critical to modern industrial operations across Australia. They design, program, commission, and maintain the automation systems that run manufacturing lines, water treatment plants, mining operations, and energy infrastructure. With Industry 4.0 adoption accelerating and a persistent skills shortage in automation, salaries for controls engineers have risen steadily. In 2026, permanent salaries range from $95,000 for graduates to $175,000+ for senior specialists, with contractor rates between $750 and $1,300 per day.

The role requires a unique combination of electrical engineering knowledge, software programming skills, and on-site commissioning experience. Controls engineers must be comfortable working both at a desk writing PLC code and on a factory floor troubleshooting a faulted drive or calibrating an instrument. This dual skill set is rare, which is why employers consistently report controls and PLC engineers as one of the hardest positions to fill in the Australian market.

Salary by Experience Level

  • Graduate / Junior (0-2 years): $85,000 to $105,000 per annum. Typically working under supervision, assisting with PLC programming, I/O testing, and basic SCADA screen development.
  • Mid-Level (3-5 years): $110,000 to $140,000 per annum. Independently programming PLCs, developing HMI/SCADA applications, commissioning control systems, and writing functional design specifications.
  • Senior (6-10 years): $140,000 to $170,000 per annum. Leading automation projects, designing control architectures, mentoring junior engineers, and managing vendor relationships.
  • Lead / Principal (10+ years): $165,000 to $200,000+ per annum. Setting automation standards, managing capital project automation packages, and providing technical governance across multiple sites or projects.

PLC Platform Premiums

Not all PLC experience is valued equally. The platform you specialise in can significantly impact your market rate:

  • Allen-Bradley (Rockwell): The most widely used platform in Australian manufacturing and mining. ControlLogix and CompactLogix experience is baseline; FactoryTalk View and PlantPAx DCS experience commands a premium of 5 to 10 percent above market.
  • Siemens (TIA Portal / S7): Strong demand in water, infrastructure, and European-owned manufacturing sites. S7-1500 and WinCC experience is particularly sought after.
  • Schneider Electric (Unity / M340 / M580): Common in water and wastewater, building management, and power distribution. Citect SCADA experience is a valuable differentiator.
  • ABB (AC500 / 800xA): Dominant in minerals processing, pulp and paper, and oil and gas. 800xA DCS experience is a premium skill commanding the highest contractor rates in the controls space.
  • Honeywell / Emerson: Primarily in oil and gas and chemical processing. Experion PKS and DeltaV experience pushes rates into the top tier.

Engineers with multi-platform experience (for example, Allen-Bradley plus Siemens) are particularly valuable because they can work across a wider range of client sites and projects.

Salary by State

  • Western Australia: $130,000 to $190,000 (mining automation, oil and gas, and lithium processing)
  • Queensland: $120,000 to $175,000 (coal handling, minerals processing, and LNG)
  • New South Wales: $115,000 to $165,000 (manufacturing, water infrastructure, and data centres)
  • Victoria: $110,000 to $160,000 (food and beverage, automotive, and pharmaceutical manufacturing)
  • South Australia: $105,000 to $155,000 (defence, water, and renewables)

Career Paths and Progression

Controls and PLC engineers have several career progression options beyond pure technical growth. Many transition into automation project management, where their technical depth gives them an advantage in scoping, estimating, and delivering control system upgrade projects. Others move into functional safety engineering (SIL assessment and SIS design), which is a niche but highly paid specialisation. Senior controls engineers with business development skills can move into pre-sales or technical consulting roles within system integrator firms, where total compensation including bonuses can exceed $200,000. The growing field of industrial cybersecurity (IEC 62443) is also drawing experienced controls engineers who want to specialise in securing OT networks and SCADA systems.
