Assistant Manager, Petro Aggregation

Assistant Manager, Petro Aggregation

Livestock, Irrigation & Mixed Farming

Northern WA | Approx. 3 hours from Perth | Accommodation and vehicle available

Ready to step into a serious hands-on leadership role?

Stone Axe Pastoral is looking for a capable, practical and switched-on Assistant Manager to help lead operations across the Petro Aggregation, covering Petro, High Hill and Wilara farms. This is a senior operational role with real ownership across irrigation, machinery, livestock, fodder production and day-to-day farm performance. 

Based in Northern WA, approximately three hours from Perth, this role offers the opportunity to live and work on a productive mixed farming aggregation, with accommodation and a vehicle available.

If you are someone who can fix the problem, run the gear, lead from the front and keep the place moving, this is the role for you.

About the Role

This is not a desk job. It is a hands-on, technically demanding role where you will work closely with the WA North Operations Manager to keep the aggregation running safely, efficiently and to a high standard. 

The role has a strong focus on centre pivot irrigation systems, cropping and fodder programs, machinery operation and maintenance, livestock operations and general farm infrastructure. You will need to be confident making decisions, solving problems, managing daily work priorities and taking ownership of operational outcomes. 

You will be trusted to get things done, keep people safe and make sure the operation runs smoothly.

What You’ll Be Doing

You will play a key role across the full operation, including:

• Taking primary responsibility for the operation, maintenance and troubleshooting of centre pivot irrigation systems. 
• Diagnosing and fixing mechanical and electrical issues across pumps, motors, gearboxes, control systems, machinery and farm infrastructure. 
• Operating and maintaining GPS-guided tractors, telehandlers, seeding equipment, haymaking machinery and other farm plant. 
• Leading cropping and fodder programs, including seeding, mowing, raking and baling. 
• Supporting day-to-day livestock operations, including joining, calving, weaning, scanning, animal health, trucking and testing. 
• Maintaining accurate livestock records, treatment records, stock reconciliations and operational reporting. 
• Carrying out fencing, water infrastructure repairs, welding, fabrication and general property maintenance. 
• Supporting and leading staff and contractors when required. 
• Promoting strong safety standards across livestock handling, machinery operation, irrigation maintenance and chemical use. 

About You

You are practical, reliable and mechanically minded. You know how to work across a mixed farming operation and you take pride in keeping things running properly.

You will bring:

• Strong experience in irrigation systems, ideally including centre pivots. 
• Practical machinery skills and the ability to diagnose and repair issues before they become bigger problems. 
• Livestock experience, with good stockmanship and confidence around day-to-day cattle operations. 
• Mechanical aptitude, problem-solving ability and sound judgement. 
• The ability to plan and execute daily and weekly work programs with minimal supervision. 
• A strong safety mindset and the ability to lead by example. 
• Good communication skills and the ability to work well with managers, staff, contractors and external specialists. 
• An HC licence, or the ability to transition to one. 

Most importantly, you are someone who takes ownership. You notice what needs doing, you care about the standard of the operation and you are prepared to roll up your sleeves.

Why Join Stone Axe Pastoral?

This is a standout opportunity for someone who wants more than a routine farm role.

You will get:

• A senior hands-on role with genuine responsibility.
• Variety across irrigation, livestock, machinery, fodder, maintenance and leadership.
• The chance to work across a mixed farming aggregation in Northern WA.
• Accommodation available with the role.
• A vehicle available for work use.
• A role where practical skill, initiative and reliability are genuinely valued.

• Has come from a mixed farming, livestock, irrigation or broadacre background.
• Is comfortable being hands-on every day.
• Can operate, maintain and troubleshoot machinery and irrigation systems.
• Has enough livestock experience to contribute confidently on the ground.
