If your pay varies week to week, you're not alone - and you're not automatically harder to approve. Whether you're on a rotating hospital roster, picking up agency shifts, running your own ABN, or earning a mix of base pay and commissions, lenders can and do approve these applications every day. What changes is how they count your income, not whether they count it at all.
That distinction matters more than most borrowers realise. The difference between a lender who takes your overtime at full value and one who shades it by 20% can move your borrowing capacity by $40,000 or more on a typical Springfield or Ipswich income. Knowing which lenders read your income which way is where the real work happens.
Our team works with buyers across Springfield and Ipswich, QLD every week who have variable, shift-based or self-employed income - comparing across 60+ lenders to find the ones whose policies actually fit. The home loan options for buyers with irregular or variable income are wider than most people expect, and the right lender is usually not the one you already bank with.
Here's what lenders actually look at when your income doesn't arrive in a neat fortnightly figure.
Key takeaways
- Lenders shade overtime and shift income differently - policy varies between lenders.
- Casual workers typically need around 12 months of consistent history to qualify.
- Self-employed borrowers usually need two years of tax returns to confirm income.
What does "irregular income" actually mean to a lender in Springfield and Ipswich, QLD?
To a lender, irregular income is any pay that isn't a fixed base salary arriving on the same date every pay cycle. That covers a wide range of real employment situations - shift penalty rates, overtime, commission, bonus, casual hourly pay, agency work, and self-employed or ABN income. Each one is assessed differently, and the policies aren't published side by side anywhere.
What they share is this: lenders want to see that the income is real, repeatable and likely to continue. A consistent pattern of overtime over 12 months carries more weight than a single strong quarter. A tax return showing two years of steady self-employed income carries more weight than a recent BAS alone.
What we see most often is borrowers who've been earning consistently for over a year but assume none of it counts because it doesn't arrive in a fixed amount. The income counts - what varies is which lender will count how much of it, and that's exactly what the comparison is for.

How do lenders assess shift income, overtime and allowances?
Shift penalties, overtime and allowances are the income types where lender policy diverges the most. Some lenders take consistent overtime at full value once you've got 12 months of history behind it. Others apply a discount of around 20%, regardless of how regular or long-running it is. That gap between 80% and 100% of your overtime is often the single largest variable in a borrowing capacity assessment.
Shift allowances and penalty rates - common among nurses at Ipswich Hospital or the Mater Springfield, paramedics, police and shift-based workers in Bundamba's industrial areas - are typically assessed on an average over a recent period rather than a peak month. Lenders look at the year-to-date figure on your payslips and confirm it against your most recent group certificate or income statement.
What most lenders want to see for variable PAYG income:
- ›Overtime: a consistent history over a recent period; most lenders average it rather than taking the best month.
- ›Shift penalties and allowances: typically assessed on an average of the documented period; year-to-date payslips and a group certificate are the evidence.
- ›On-call and standby: accepted by some lenders where it is a formal contractual component, more contested where it is ad hoc.
- ›Second job: most lenders accept a secondary income once a consistent history is established in the same field; the history requirement is usually longer than for the primary role.
How do lenders treat casual and agency work?
Casual and agency workers can qualify for a home loan, but lenders want to see that the work is genuinely ongoing rather than occasional. Around 12 months of consistent casual history in the same field is the typical threshold - not 12 months at the same employer necessarily, but 12 months in the same kind of work. A casual teacher, a casual nurse doing agency shifts, or a casual logistics worker who's been consistently employed through the same agency all tend to read well once that history is there.
What complicates the picture is a recent change in employer or field. A casual worker who has been in the same role for 18 months is in a much stronger position than one who started a new casual role three months ago, even if the hourly rate is higher. Lenders assess the pattern, not just the latest payslip.
Agency shifts are assessed similarly to casual pay - the agency is the employer for assessment purposes, and a consistent booking history through the same agency is what supports the application. Some lenders are more comfortable with long-term agency arrangements than others, and that's one of the policy differences worth comparing before you apply.
How much can you borrow in Springfield and Ipswich, QLD with irregular income?
Your borrowing capacity with variable income depends on which income types the lender will count, at what percentage, and over what period. The APRA serviceability buffer of 3.0% is added to the assessment rate on top of all of that - so your income is both potentially discounted and assessed against a rate of approximately 9%. That combination is why lender choice matters so much for variable-income borrowers.
The options worth weighing:
- ›Lender A (generous variable-income policy): overtime at full value · 12-month history required · agency income accepted · higher borrowing result
- ›Lender B (conservative variable-income policy): overtime shaded to around 80% · longer history preferred · agency income assessed cautiously · lower borrowing result
- ›Non-bank lender: more flexible income assessment in some cases · not subject to the APRA DTI cap · rate typically higher than bank equivalents
In Springfield and Ipswich, where house medians range from around $700,000 in Booval and Riverview to over $900,000 in Camira and Spring Mountain, the lender that reads your income most favourably can be the difference between qualifying for a suburb you want and settling for one you don't.

How do lenders assess commission and bonus income?
Commission and bonus income are accepted by most lenders, but they're averaged over time rather than taken at the current month's figure. Most lenders want to see one to two years of consistent bonus or commission history before they'll count it, and they typically assess it at somewhere between 80% and 100% of the averaged amount. A single exceptional bonus year is unlikely to move the number significantly - the second year is what gives it weight.
The practical implication is that a borrower who has just moved into a commission-heavy role is assessed quite differently from one who has been in the same field for two years with a consistent commission history. If you're early in that pattern, it may be worth timing your application to give the income history more weight.
How do lenders assess self-employed and ABN income in Springfield and Ipswich, QLD?
Self-employed borrowers - whether sole traders, company directors, or trust beneficiaries - are generally assessed on two years of tax returns as the standard approach. Lenders use the net taxable income as the base, and some will add back certain non-cash deductions like depreciation to arrive at a higher assessable figure. That add-back is one of the most significant policy differences between lenders, and it varies considerably.
What lenders look for in a self-employed application
The two-year history requirement exists because lenders want to see that the business income is stable, not just that it had a good year. Where the second year is significantly lower than the first, lenders typically use the lower figure. Where it's significantly higher, some lenders will average the two; others will use the most recent.
When one year of returns is enough
Some lenders will consider a self-employed application with one year of tax returns, usually where the business has been operating longer and the applicant can show an accountant's letter confirming the income is sustainable. This is a narrower panel of lenders and the conditions attached are usually more specific - it's worth a conversation before assuming it applies to your situation.
What a self-employed application typically requires:
- ›Tax returns: two years of personal and, where applicable, company or trust returns.
- ›Notices of assessment: ATO-issued assessments confirming the lodged returns for the same period.
- ›BAS statements: most recent quarters, confirming the business is trading and income is continuing.
- ›Business bank statements: typically three to six months, showing consistent turnover.
- ›Accountant's letter: required by some lenders; particularly useful where there's an income spike or an unusual deduction in the returns.
When does irregular income make getting a home loan harder?
Irregular income isn't an automatic problem, but there are situations where it genuinely complicates things. If you've recently changed industries, your income history in the new field starts from zero regardless of what came before. A nurse who's moved from a hospital role to a staffing agency, or a tradie who's gone from PAYG to ABN in the past six months, will typically wait longer before a lender treats that income as established.
Very high variability is also harder to work with. A borrower whose income swings significantly between months - where the low months are substantially below the average - gives lenders less confidence than one whose variable component is more predictable. In those cases, the base salary component carries the application and the variable part adds what it can once history supports it.
If your income is genuinely unpredictable, it's usually better to apply when the history is strongest rather than when the need is most urgent. Timing an application after a strong consistent period is one of the more useful things a broker can identify for you.
Where I'd push back on a client is when they want to apply right now because they've found a property, but their income history only shows three strong months. A lender sees that as a short trend, not an established pattern. Waiting one more reporting period is often the better call - and it usually results in a cleaner approval at a better rate.

How to get a home loan with irregular income in Springfield and Ipswich, QLD, step by step
The process is the same as any home loan application - what changes is which lender is right for your income type and how your documentation is prepared. Getting that match right before you apply is what avoids an unnecessary decline on your credit file.
Step 1: Talk to us
We start by mapping your income - what types you earn, how consistent the history is, and which lenders on our panel read that combination most favourably.
Step 2: Gather your income evidence and assess your position
We work through what documentation your income type requires - payslips, group certificates, tax returns, BAS, bank statements - and identify any gaps before an application goes anywhere.
Step 3: Match to the right lender and prepare the application
We select the lender whose policy gives your income the strongest assessment, prepare the application with the right framing, and submit it with the full documentation package from the start.
Step 4: Manage the approval through to settlement
We liaise with the lender through the assessment process, handle any follow-up requests for information, and keep you informed at each stage through to settlement.
What approval challenges do buyers with irregular income face?
The hurdles that come up most often:
- ›Insufficient income history: applying before the 12-month or two-year threshold is met is the most common reason a variable-income application is declined or comes back at a lower borrowing figure than expected.
- ›Applying to the wrong lender first: a lender with a conservative variable-income policy will assess the same application at a materially lower income than one with a generous policy. A decline on the wrong lender sits on your credit file for five years.
- ›Incomplete documentation: missing a BAS quarter, a group certificate, or an accountant's letter can hold an application in assessment for weeks or trigger a conditional approval that delays settlement.
- ›Credit card limits reducing capacity: lenders assess credit card limits as if they're fully drawn, at around 3% to 3.8% of the limit per month. A $20,000 card limit is treated as a significant ongoing commitment regardless of the actual balance - reducing limits before applying is worth considering.
Frequently Asked Questions
Can I get a home loan on casual income in Springfield and Ipswich?
Yes, casual workers can qualify with around 12 months of consistent history in the same field. Lenders assess the average income over that period rather than the most recent payslip alone.
Do lenders count all of my overtime when assessing my home loan?
Not always - some lenders take consistent overtime at full value while others shade it to around 80%. The difference between those two positions is often tens of thousands of dollars in borrowing capacity.
How long do I need to be self-employed before I can get a home loan?
Most lenders require two years of tax returns. A small number will consider one year where an accountant's letter confirms the income is sustainable, but the panel for that is narrower.
Is a professional LMI waiver available to shift workers or casual employees?
Professional LMI waivers are tied to occupation rather than income type. A registered nurse on agency shifts may qualify for a waiver based on their registration, regardless of their casual employment status. Whether it's available depends on which lenders your broker has access to and your specific circumstances.
Will applying to multiple lenders hurt my credit score?
Each application leaves an enquiry on your credit file for five years. Comparing through one broker means one assessment of your position rather than multiple applications - which is how you avoid accumulating enquiries before a lender sees your file.
Should I use a mortgage broker or go directly to my bank if I have irregular income?
A mortgage broker, every time. Variable-income policy differs significantly between lenders and your own bank is one option, not a benchmark. A broker compares across the panel and finds the lender whose policy reads your income most favourably before any application is submitted.
Your Next Steps
Getting your home loan right with irregular income is about finding the lender whose policy actually fits your income shape - and that's a comparison that's almost impossible to make from the outside without knowing each lender's current assessment rules.
