How Australian Lenders Assess Foreign Income — The Complete Expat Guide

The single biggest factor in your borrowing capacity as an expat is not the size of your salary — it is how your lender assesses it.

Two expats with identical incomes in different currencies can have borrowing capacities that differ by hundreds of thousands of dollars, purely based on how their lender treats foreign currency income. Understanding this is essential before you start looking at properties.

What Is Income Shading?

Income shading is the process by which Australian lenders reduce a foreign currency income for serviceability purposes. Rather than accepting 100% of your overseas earnings (after converting to AUD), most lenders apply a shading percentage — accepting only a portion of your converted income when calculating how much you can borrow.

The shading exists because lenders assess currency risk, employment stability, and the regulatory environment in your country of employment. The higher they perceive the risk, the lower the percentage of income they will accept.

Currency Tiers

Lenders categorise foreign currencies into tiers. Your tier determines your shading rate:

Tier	Currencies	Typical income acceptance
Tier 1	SGD, USD, GBP, EUR, HKD, JPY, CAD, NZD, CHF	80–90% of AUD-converted income
Tier 2	AED (UAE Dirham), SAR, QAR, MYR, and others	60–80% of AUD-converted income
Tier 3	Other currencies not listed above	50–60% or may be declined

Tier classifications vary by lender — a currency classed as Tier 1 by one lender may be Tier 2 by another. This is one of the most important reasons to use a broker who specialises in expat lending: knowing which lender applies the most favourable treatment to your specific currency can meaningfully increase your borrowing capacity.

How Currency Conversion Works

Lenders convert your foreign income to AUD before applying the shading rate. Most lenders use either:

• The current exchange rate at the time of application, or
• A conservative rate (often 3–5% below spot) to account for currency fluctuation risk

Some lenders apply both a conservative conversion rate AND a shading percentage — compounding the reduction. This is why the lender selection matters so much for expat borrowers.

Worked Example — SGD Borrower

Annual salary (SGD)	SGD 200,000
AUD conversion (at 0.91)	AUD 218,000
Lender shading applied (80%)	AUD 174,400 used for serviceability
vs Australian-resident equivalent	AUD 218,000 used (100%)
Estimated borrowing capacity difference	~$150,000–$250,000 less than a comparable Australian resident

Other Income Types — What Lenders Accept

Beyond base salary, lenders treat additional income sources differently for expat borrowers:

• Bonuses and commissions: Most lenders accept 50–100% of documented bonuses, averaged over 2 years. Foreign currency bonuses are also shaded.
• Rental income (Australian property): Generally accepted at 75–80% of gross rental income (same as Australian residents).
• Investment income: Dividends, trust distributions — accepted with documentation, typically at 100% if in AUD.
• Spouse/partner income: If your co-borrower is based in Australia, their income is assessed at full Australian resident rates.

Documentation Required

For a foreign income assessment, lenders typically require:

• 2–3 months’ payslips in the foreign currency
• A letter of employment confirming salary, tenure, and employment type
• 2 years of tax returns (where available in your jurisdiction)
• Bank statements showing salary deposits
• For self-employed borrowers: company financials, accountant’s letter, proof of business registration

How to Maximise Your Borrowing Capacity as an Expat

• Choose a lender that classifies your currency as Tier 1 and applies the highest shading rate
• Consider a co-borrower based in Australia (if applicable) to improve the serviceability calculation
• Document all income sources thoroughly — bonuses, allowances, rental income
• Minimise existing debts and credit cards before applying — the APRA DTI cap (effective February 2026) limits high-DTI lending
• Use a specialist expat mortgage broker who knows which lenders are most competitive for your specific currency and employment profile
