Quick Answer
Mobilisation means getting your people, plant and paperwork onto site and cleared to start work. In Australian mining it covers selecting the crew, completing site inductions, verifying licences, VOCs and medicals, arranging travel and accommodation, issuing PPE, lodging contractor documentation and obtaining site access. Mobilisation finishes the moment the crew is legitimately on site and productive.
- Workers — named crew, roles, roster and a nominated site lead.
- Compliance — inductions, licences and tickets, VOCs, medicals, drug and alcohol screening.
- Logistics — flights or drive-in plans, camp or town accommodation, freight of plant and tools.
- Kit — site-standard PPE plus task-specific gear, fit tested where required.
- Access — approved access requests, vehicle permits, gate passes and portal approvals.
- Timeline — two to six weeks for a new site; medicals and VOCs are the long poles.
Mobilisation, defined
Outside mining, mobilisation simply means organising people and resources for a task. In mining and heavy industry contracting it has a much sharper meaning: the period of work and cost between winning a scope and having a compliant crew doing productive work on site. Nothing in that window is billable production, and almost everything in it can stop the job from starting.
The reverse process at the end of a scope is demobilisation — returning workers home, removing plant, cleaning and handing back the work area, closing permits, returning passes and finalising costs. Most contracts price and schedule the two together.
What mobilisation involves for mining contractors
Every mine operator words it differently, but the elements are consistent. Any one of these missing on the day of travel will turn a worker away at the gate.
| Element | What it means in practice |
|---|---|
| Workers | Confirming who is actually going: names, roles, crew structure, shift pattern, availability against other jobs, and a nominated supervisor or site lead for the scope. |
| Inductions | Generic construction (white card) where relevant, plus the site operator's own induction, standard 11 or site-specific modules, area inductions and any contractor portal onboarding before anyone drives through the gate. |
| Licences and tickets | High risk work licences, HR/HC/MC driver licences, working at heights, confined space, EWP, rigging, dogging, electrical licences, plus state-specific mining tickets. All in date on the day of travel, not the day of the tender. |
| VOCs | Verification of competency on the specific plant or task at that site — often assessed by the site or a third party, and usually only valid for a set period and machine type. |
| Medicals | Pre-employment or site medicals, coal board medicals in Queensland and NSW where required, audiometric testing, respiratory and other health monitoring, plus drug and alcohol screening. |
| Travel | Flights or drive-in plans, bus and charter bookings, rosters aligned to flight days, journey management plans and fatigue rules for long drives to remote sites. |
| Accommodation | Camp rooms or town accommodation booked and confirmed against the roster, meal arrangements, and who is paying — the client, you, or a labour hire arrangement. |
| PPE | Site-standard hi-vis with reflective tape, safety boots, hard hat, glasses, gloves, hearing protection, plus task-specific gear like FR clothing, harnesses, gas monitors and respirators — fit tested where required. |
| Site access | Access requests submitted, vehicle permits, light vehicle compliance and inspections, gate passes, swipe cards, contractor portal approvals and any pre-mobilisation audit. |
| Plant, tools and consumables | Machines and vehicles registered on site, pre-starts and service records current, lifting gear tagged and in test date, tools calibrated, and consumables shipped ahead of the crew. |
| Documentation | SWMS, JSAs, risk assessments, ITPs, insurances, licences to work, contractor management pack and emergency contacts lodged and accepted before work starts. |
Where the obligations come from
You keep your WHS duties on someone else's site
As a PCBU you must ensure the health and safety of your workers so far as is reasonably practicable, and you share duties with the site operator. Mobilisation is where that duty is discharged: competence verified, risks assessed, and consultation and coordination with the mine operator documented before work begins.
Mining regulations add site-specific requirements
Queensland coal and mineral mines, WA operations under the WHS (Mines) Regulations and NSW sites under the Resources Regulator each set their own induction, competency, medical and contractor onboarding expectations. The site's safety and health management system usually goes beyond the general WHS minimum.
Health monitoring and medicals are regulated
Coal mine worker health assessments in Queensland and NSW, respirable dust and noise monitoring, and hazardous chemical health monitoring have defined content, providers and record-keeping obligations. Track the assessment date and next-due date, not just the certificate.
Travel, hours and fatigue are part of the picture
Long drive-ins, flight days and 12-hour shifts bring fatigue management and Fair Work considerations — award interpretation, travel allowances, LAFHA arrangements and rest between shifts. Get these decided at mobilisation, not in the first pay run.
Confirm the detail with Safe Work Australia and your state regulator — Resources Safety & Health Queensland, DEMIRS (WA) or the NSW Resources Regulator — plus the Fair Work Ombudsman for travel, allowances and hours, and the site operator's own contractor management requirements.
A mobilisation timeline that works
Confirm the scope and the mobilisation date
Get the start date, duration, roster, site, work area and the client's contractor requirements in writing. Everything else works backwards from that date.
Pick the crew and check their compliance
Run every nominated worker against the site's requirements: inductions, licences, VOCs, medicals and expiries that fall inside the campaign. Fix gaps now, not the night before.
Book the training, VOCs and medicals
These have the longest lead times. Coal board medicals, site inductions and third-party VOCs can take weeks, so they are the first thing to schedule and the most common reason a mobilisation slips.
Lodge access and contractor documentation
Submit insurances, SWMS, risk assessments and licences into the client's contractor portal and allow time for review, questions and resubmission.
Book travel and accommodation
Flights, buses or drive-in journey plans matched to the roster, camp rooms confirmed, and a plan for changeovers and unplanned extensions.
Issue PPE and prepare plant
Kit each worker to the site's standard, and get vehicles, machines and lifting gear inspected, tagged, registered and shipped so they arrive before the crew.
Hold a pre-mobilisation review
One meeting, one checklist: every worker cleared, every document accepted, travel booked, plant on site, scope understood. Sign it off before anyone leaves home.
Mobilise and verify on arrival
Site induction, area induction, take-5s and pre-starts on day one, and confirm the crew list on site matches the crew list you cleared.
Track it as a cost
Mobilisation hours, travel, accommodation, training and freight are real costs. Capture them against the job so the next quote is priced on evidence.
Best practice for contractors
Keep one live compliance profile per worker
Every licence, ticket, VOC, medical and induction against the person with an expiry date, so clearing a crew for a site is a filter rather than a fortnight of phone calls.
Build a per-client mobilisation checklist
Each mine operator wants something slightly different. Store their requirements once and reuse the checklist every time you mobilise there.
Alert on expiries 60 and 30 days out
Most mobilisation failures are an expiry nobody saw. Automated warnings turn a crisis into a booking.
Check expiries against the whole campaign
A ticket valid on day one but expiring mid-swing will demobilise a worker halfway through. Validate against the end date of the roster.
Give the field a single crew pack
Rosters, flights, camp details, site contacts, SWMS and inductions on the phone, available offline, so the crew is not chasing an email in a dead spot.
Cost mobilisation separately in your quotes
Training, medicals, travel, accommodation, freight and non-productive travel time are frequently absorbed. Quote them as a line item and measure them against actuals.
Common mobilisation mistakes
Discovering an expired ticket at the gate
The worker is turned away, the crew is short, and the client sees it. It is almost always avoidable with expiry tracking.
Leaving medicals and VOCs to the last fortnight
These have the longest lead times of anything in a mobilisation and cannot be rushed.
Treating mobilisation as free
Travel, accommodation, training and freight quietly eat margin when they are not quoted and not tracked against the job.
Compliance records living in one person's inbox
When the coordinator is on leave, the mobilisation stalls. Records belong against the worker in a system.
No plan for changeovers and extensions
Scopes extend. Without a rolling roster and a cleared standby pool you are mobilising from scratch every time.
Assuming last site's induction covers this one
Inductions and VOCs are usually site and machine specific, and rarely transfer.
