Lenders assess your income differently when you work FIFO.
Most lenders use a base salary plus allowances model, but the way they treat your roster allowances, overtime, and site-specific payments varies between every lender. Some will accept 100% of your FIFO allowances as income, others discount it by 20%, and a few won't count irregular payments at all. That gap can change your borrowing capacity by $100,000 or more.
How Lenders Calculate FIFO Income for Fixed Plant Operators
Lenders calculate your income using payslips and employment contracts, then apply their own serviceability formulas to determine how much you can borrow. For a fixed plant operator on a two-week-on, one-week-off roster earning a base of $90,000 plus allowances that push total income to $130,000, one lender might assess you at $130,000 while another caps it at $105,000 by excluding or discounting the allowances.
Your employment contract is the starting point. Lenders want to see a permanent contract that clearly separates base salary from allowances. If your contract lists a single annual figure without breaking down what's guaranteed versus what's roster-dependent, expect the lender to take a conservative view. We regularly see operators with strong incomes get assessed lower than necessary because their contract doesn't itemise payments clearly.
Payslips for the most recent three months confirm what you're actually receiving. Lenders look for consistency across those payslips. If your overtime or shift allowances fluctuate significantly between pay periods, some lenders will average them, others will take the lowest figure, and a few won't count them at all. That's why a plant operator with stable allowances will borrow more than someone earning the same total income but with variable payments.

What Documentation You Need to Provide
You need payslips for the last three months, your current employment contract, and recent tax documentation. Most lenders also want to see your roster to confirm your work pattern aligns with the income you're declaring. If you've been in the role for less than 12 months, expect to provide payslips from your previous employer as well.
Your most recent tax return or notice of assessment gives lenders a year-end view of your income. If your payslips show higher earnings than your last tax return because you've had a pay rise or moved to a higher-paying roster, the lender will usually accept the current payslips as long as your contract supports it. The reverse situation, where your tax return shows more income than your current payslips, means the lender will assess you on the lower current figure.
For operators who've recently started a new FIFO role, some lenders require a minimum employment period before they'll assess your full income. That period ranges from three months to 12 months depending on the lender. If you've been in your role for less than six months, expect fewer lenders to be available and potentially higher interest rates until you pass the 12-month mark.
How Employment Type Affects Your Application
Permanent employment gives you access to the widest range of lenders and the lowest rates. Casual and contract roles are treated differently, and the distinction matters when you're applying for a home loan as a FIFO fixed plant operator.
If you're employed on a casual basis, most lenders require at least 12 months of continuous employment with the same employer before they'll assess your income at the full rate. Even then, they typically discount casual income by 20% to account for the lack of job security. A casual plant operator earning $130,000 might only be assessed at $104,000, which directly reduces how much you can borrow.
Contract workers face similar restrictions. If you're on a fixed-term contract with six months or less remaining, many lenders won't proceed with an application unless you have a letter from your employer confirming an extension or conversion to permanent. That's a problem if your employer doesn't issue those letters until closer to the contract end date. In that scenario, you either wait or work with a lender that accepts shorter contract terms, usually at a higher rate.
Variable Income and How It's Treated
Variable income includes overtime, bonuses, and irregular shift loadings. Lenders treat these payments as secondary income and apply different rules depending on how consistent they are.
Consider a plant operator who earns a base of $95,000 plus overtime that varies between $15,000 and $35,000 per year depending on site demands. Most lenders will average the overtime over two years of tax returns, then shade that average by 20%. If your overtime averaged $25,000 across the last two years, the lender might only count $20,000 of it. That's a $5,000 reduction in assessed income, which translates to roughly $30,000 less in borrowing capacity depending on your other commitments.
Bonuses are handled the same way. If you receive an annual performance bonus that's discretionary, lenders will either exclude it entirely or average it over two years and apply a discount. The only exception is when your employment contract guarantees the bonus and specifies the amount or formula. In that case, it's treated as part of your base income.
Changing Jobs While Applying for a Loan
Changing employers mid-application will pause your approval until you've completed probation with the new employer. Most lenders require three months of payslips from the new role before they'll proceed, even if you're doing the same work for a different mining company.
If you're considering a job change and you're already in the early stages of a home loan application, it's usually worth finishing the application process first. Once you're formally approved and contracts are exchanged, a job change has less impact as long as you can demonstrate ongoing income. But if you switch jobs before the lender issues formal approval, you're effectively starting the application again.
The exception is when you're moving to a higher income or more secure employment. If you're going from casual to permanent or taking a role with a significant pay increase, some lenders will work with you during probation if you can provide a signed contract and evidence that you've started the role. That's not universal, so expect fewer options and potentially a delay in settlement.
How Lenders View Shift Rosters and Leave Entitlements
Your roster structure affects how lenders assess your income stability. A fixed plant operator on an even-time roster with consistent pay periods is viewed more favourably than someone on an ad-hoc or project-based roster where pay fluctuates.
Lenders also look at your leave entitlements. If you've accrued significant annual leave or long service leave, that's seen as a positive indicator of employment stability. It doesn't increase your borrowing capacity, but it does support your application by showing you've been with the employer long enough to build entitlements. Conversely, if you have no accrued leave because you're new to the role, the lender will rely more heavily on your employment contract and probation status.
Some operators take unpaid leave between rosters or during project downtime. If that unpaid leave appears on your payslips, it can raise questions about income consistency. Lenders may ask for a letter from your employer explaining the leave and confirming it's not a regular occurrence. If unpaid leave is a regular part of your roster, expect your income to be assessed lower to account for those gaps.
Improving Your Application Before You Apply
Get your employment contract updated if it doesn't clearly break down your income components. A contract that lists base salary, roster allowances, and any guaranteed payments separately gives lenders the information they need to assess you at your full income. If your contract is vague or outdated, ask your employer to issue a letter of employment that specifies your current salary structure.
Ensure your payslips are consistent across the most recent three months. If you've had a pay rise, taken unpaid leave, or received a one-off payment, be prepared to explain it. Lenders assess patterns, and anything that disrupts the pattern will trigger questions. Providing context upfront, such as a letter from your employer or a copy of your roster, reduces the chance of delays.
If you're planning to apply for loan pre-approval, do it while your income and employment are stable. Pre-approval is based on the information you provide at the time, so if your circumstances change before settlement, the lender will reassess. Applying during a period of consistent income and secure employment gives you the strongest position.

Frequently Asked Questions
Do lenders count all of my FIFO allowances as income?
It depends on the lender. Some accept 100% of your roster allowances, others discount them by 20%, and a few exclude irregular payments entirely. The difference can change your borrowing capacity by $100,000 or more.
What documents do I need to apply for a home loan as a fixed plant operator?
You need three months of payslips, your current employment contract, recent tax documentation, and often a copy of your roster. If you've been in the role for less than 12 months, you may also need payslips from your previous employer.
Can I apply for a home loan if I'm on a casual FIFO contract?
Yes, but most lenders require at least 12 months of continuous employment and will discount your income by around 20%. This reduces your borrowing capacity compared to permanent employees earning the same amount.
What happens if I change jobs while applying for a home loan?
Changing employers mid-application will pause your approval until you complete probation with the new employer. Most lenders need three months of payslips from the new role before they'll proceed, even if you're doing the same work.
How do lenders treat overtime and bonuses for FIFO workers?
Lenders usually average overtime and bonuses over two years of tax returns, then apply a 20% discount. If a bonus is guaranteed in your contract, it may be treated as part of your base income without a discount.
