Becoming a Medical Emergency Services Officer (MESO/ESO)

Whether you’re already working in a fly-in-fly-out job in the mining sector, or looking to join the booming industry, becoming a Medical Emergency Services Officer (MESO/ESO) could be a rewarding career pathway for you. 

What is a Medical Emergency Services Officer (MESO/ESO)?

A Medical Emergency Services Officer (MESO) or Emergency Services Officer (ESO) is typically responsible for medical care (and sometimes fire rescue, security, training and WHS) on large industrial sites, particularly mine sites.

Generally sitting within the mine safety team, most sites have medics on-site to assist in the medical treatment of both minor and major injuries as well as offer basic life support when needed.

For many people, becoming a MESO/ESO is a popular alternative to becoming a Paramedic. While the scope of work may be different, both jobs have similar skill sets, and offer an opportunity to make a difference by providing emergency medical care.

MESOs can hold different titles, such as:

  • Emergency Services Officer (ESO)
  • Mine Site Medic
  • Industrial Medic
  • Underground Medic
  • Mine Rescue Medic
  • Emergency Response Coordinator

What industries does a MESO/ESO work in?

With skills in security, fire, rescue and medical, MESO/ESOs are valuable employees across a range of industries, including:

  • Mining and metalliferous (above and underground)
  • Maritime
  • Power and energy
  • Industrial
  • Offshore oil and gas
  • Defence
  • Aviation
  • Construction

Typical duties of a MESO/ESO

The duties of a MESO/ESO will vary depending on the size and location of the site you’re working on, your qualifications and the scale of the team/workforce you are responsible for.

Typical duties you may be required to undertake include:

  • Injury management including liaising with patients, doctors and physiotherapists
  • Undertaking random drug and alcohol testing
  • Responding to minor or major on-site injuries and providing medical care
  • Administer basic life support if necessary
  • Mental health assessments and recommendations
  • Responding to vehicle accidents, and much more

Average MESO/ESO salary

The average salary for a MESO/ESO in Australia is $110,000 – $140,000 per year.*

This amount may increase depending on your level of experience, industry you’re working in, overtime and additional allowances throughout the year.

How to become a MESO/ESO

Australian Paramedical College can help you build the foundational knowledge and practical skills you need to become a trusted MESO or ESO.

Generally, you’ll need to hold at least a HLT41120 – Certificate IV in Health Care to become a MESO.

However, the HLT51020 – Diploma of Emergency Health Care could give you a competitive advantage when applying for jobs, especially if you’re looking to explore other career pathways one day. It’s worth noting that some employers may require you to also hold further qualifications, like the Certificate III in Mines Rescue.
