OVERVIEW
Australia hosts approximately 80,000–100,000 people of Indonesian origin (ABS census data), with communities concentrated in Sydney (primarily northwestern suburbs), Melbourne (inner suburbs), and Perth (due to geographic proximity — Perth is closer to Bali than to Sydney). Indonesian-Australians include a mix of migration waves: Indonesian-Chinese Australians (many of whom migrated post-1998 Indonesian crisis), economic migrants and skilled professionals, Indonesian students who remained in Australia after graduation, and partners of Australian nationals. Indonesian tourism to Australia is significant, but the permanent diaspora is smaller than comparable Southeast Asian communities. The Australia-Indonesia economic relationship is substantial: Australia is Indonesia's major investment and trade partner; Australian mining, agricultural, and education sectors employ significant Indonesian-origin professionals. The IDR has depreciated substantially against the AUD over decades — a material factor in AUD/IDR remittance value.

Individual taxpayer identification number (NPWP) required for tax registration. Employee social security: BPJS Ketenagakerjaan (JHT 5.7% combined, JP 3% combined) and BPJS Kesehatan (health, 5% combined). Currency: Indonesian Rupiah (IDR), approximately IDR 12,456 per AUD (ECB reference rate of 2 October 2026; all AUD conversions on this page use this rate). IDR has depreciated significantly vs AUD over long periods.

🇦🇺
COUNTRY B
Australia
TAX RATE
0–45%
Progressive Income Tax + Medicare Levy + Superannuation

Australia taxes residents at progressive rates: 0% (up to AUD 18,200 tax-free threshold), 15% (AUD 18,201–45,000), 30% (AUD 45,001–135,000), 37% (AUD 135,001–190,000), 45% (above AUD 190,000) for FY2026-27. Medicare Levy: 2% on taxable income. Superannuation Guarantee (employer): 12% of ordinary time earnings (2025–26 and 2026–27). Non-residents pay 30% from the first dollar (up to AUD 135,000) with no tax-free threshold. Australia taxes residents on worldwide income. The Australia-Indonesia Double Taxation Agreement (1992) prevents double taxation for residents with income in both countries.

TYPICAL ANNUAL DIFFERENCE
Moving from Australia → Indonesia at AUD 70,000 annual (Australia)
Australian wages typically 5–10x Indonesian equivalents; IDR long-term depreciation makes AUD remittances progressively more valuable

The Indonesia-Australia comparison involves significant wage differentials and a long-term currency depreciation story. The IDR has depreciated approximately 60% vs AUD over the past 20 years (from approximately IDR 6,000/AUD in 2004 to IDR 10,000+/AUD in 2024). AUD savings remitted to Indonesia buy progressively more IDR over time — a significant long-term financial advantage for Indonesian-Australians sending money home. Indonesia's top rates (30% for most earners) are lower than Australia's, but at the AUD-equivalent incomes in the table (AUD 50,000–150,000) Indonesia's total burden (PPh 21 plus employee BPJS, from our verified Indonesia calculator) is higher than Australia's income tax plus Medicare levy; Indonesia only comes out slightly lower from about AUD 190,000. The wage differential also means Australian absolute income is far higher.

Tax Savings by Income Level

Net take-home after all income tax, social contributions, and surcharges — for a single employee with no dependents.

GROSS INCOME

🇦🇺 AU TAX
SAVINGS
10-YEAR
AUD 50,000
~20% ID (about IDR 620M equivalent at IDR 12,456 per AUD — mid brackets + BPJS)
~13% AU (15% and 30% brackets + 2% Medicare; tax-free threshold reduces effective rate)
Australia clearly lower effective tax at this income (~13% vs ~20%); but Indonesian wages at this level are senior management
IDR/AUD depreciation: AUD 50,000 worth approximately IDR 350M in 2004 vs IDR 620M+ today — remittance purchasing power in Indonesia grew significantly
AUD 90,000
~25% ID (about IDR 1.12B at IDR 12,456 per AUD — 30% bracket + BPJS)
~21.5% AU (30% bracket + 2% Medicare)
Australia lower effective tax at this income (~21.5% AU vs ~25% ID)
Australia Superannuation: 12% employer contribution on AUD 90,000 = AUD 10,800/year in Super — no Indonesian equivalent for Australian-earned Super
AUD 150,000
~27.6% ID (about IDR 1.87B at IDR 12,456 per AUD — 30% bracket + BPJS caps)
~26.4% AU (37% bracket + 2% Medicare)
Broadly similar at this income (~27.6% ID vs ~26.4% AU); Indonesia comes out slightly lower from around AUD 190,000 (~28.4% ID vs ~29.0% AU), where Australia's 45% top rate starts to bite
Australia capital gains 50% discount for assets held 12+ months — no equivalent in Indonesia (25% flat rate on capital gains)

Indonesia Pros & Cons

+ PROS
  • Indonesia's PPh top rate for most earners (30%, with 35% only above IDR 5 billion) is well below Australia's 45% + 2% Medicare top rate
  • Indonesia's rapid economic growth creates professional opportunities in Jakarta's financial, tech, and energy sectors at internationally competitive salaries
  • Lower cost of living: Jakarta, Bali, and Surabaya offer high-quality living at significantly lower cost than Sydney or Melbourne
  • IDR long-term purchasing power for domestic consumption is stable despite currency depreciation — Indonesian goods and services remain affordable
  • Significant Indonesian-Chinese business networks in Australia and Indonesia create cross-border business opportunities
− CONS
  • IDR has depreciated approximately 60% vs AUD over 20 years — savings held in IDR lose AUD-equivalent purchasing power over time
  • Outside Jakarta's financial and tech sector, Indonesian wages are typically 5–10x lower than Australian equivalents
  • Indonesian banking system has limited international integration; capital controls can affect large AUD-to-IDR transfers
  • Indonesia's public healthcare (BPJS Kesehatan) quality below Australian Medicare standard — private health insurance necessary for quality care
  • Indonesia's formal employment sector is relatively small; informal economy income can be difficult to document for remittance and banking purposes
🇦🇺

Australia Pros & Cons

+ PROS
  • Australian wages typically 5–10x Indonesian equivalents across most professional categories
  • Superannuation: 12% employer-mandated retirement contribution provides significant retirement savings accumulation
  • Medicare universal healthcare at no point-of-use cost — high value for Indonesian-Australians with family dependents
  • AUD is a major international reserve currency with strong purchasing power vs IDR — AUD savings grow in IDR value over time
  • Strong Indonesian-Australian community networks in Sydney (northwestern suburbs: Strathfield, Burwood) and Melbourne provide cultural support
− CONS
  • Australia's income tax + Medicare reaches 47% at the top rate — among the highest in the Asia-Pacific region
  • Australian cost of living (housing in Sydney and Melbourne) is among the highest in the world
  • ATO's worldwide income taxation means Australian residents with Indonesian rental income, business interests, or investments must report Indonesian income to the ATO
  • Indonesian banking restrictions can complicate large AUD-to-IDR transfers — Bank Indonesia manages the IDR and monitors large cross-border flows
  • Superannuation preservation age (60) means Australians cannot access Super before that age even if they relocate to Indonesia
FAQ

Frequently Asked Questions

How do Indonesian-Australians send money to Indonesia, and does IDR depreciation matter?

AUD-to-IDR transfers are well-served by multiple providers. Western Union and MoneyGram have extensive Bank Central Asia (BCA), Mandiri, and BRI agent networks in Indonesia. Remitly and World Remit also serve the corridor. Bank transfers via SWIFT to Indonesian bank accounts are straightforward for amounts below Bank Indonesia reporting thresholds. IDR depreciation is a real long-term factor: an Indonesian family receiving AUD 500/month in 2004 received approximately IDR 3,000,000 (IDR 6,000/AUD). The same AUD 500 today delivers approximately IDR 6,200,000 (about IDR 12,456/AUD, ECB reference rate of 2 October 2026) — roughly a 108% increase in IDR-denominated purchasing power from the same AUD amount. For Indonesian-Australians supporting family in Indonesia, this long-term depreciation has made each AUD transfer progressively more valuable in domestic Indonesian purchasing power.

Does Australia tax Indonesian rental income for Australian residents?

Yes — Australia taxes Australian residents on worldwide income, including Indonesian rental income. An Australian resident who owns property in Bali, Jakarta, or elsewhere in Indonesia must report Indonesian rental income on their Australian tax return (Form I). Under the Australia-Indonesia DTA (1992), Indonesian withholding tax paid on the rental income (typically 20% for non-residents, or lower if DTA applies) can be claimed as a Foreign Tax Credit (FTC) against Australian tax liability on the same income. Practically: if Indonesian withholding tax is 20% and Australian marginal rate on the rental income is 30%, you pay 20% in Indonesia and an additional ~10% to the ATO (the difference). If Indonesian tax exceeds Australian tax on that income, no additional Australian tax is payable. Indonesian rental income must be converted to AUD at the prevailing exchange rate when reporting to the ATO.

How does Indonesia's tax system treat Australian expats working in Indonesia?

Australian nationals working in Indonesia for 183+ days in any 12-month period are Indonesian tax residents, taxed on their worldwide income in Indonesia. Australian nationals working in Indonesia for less than 183 days may be non-residents for Indonesian purposes, paying Indonesian tax only on Indonesian-source income (typically at a 20% non-resident withholding rate). Under the Australia-Indonesia DTA, employment income is taxable where the work is performed — Australian expats in Indonesia working for Indonesian employers pay Indonesian PPh (not Australian income tax) on their Indonesian employment income. Australian superannuation contributions continue to be made for Australian employees even while working abroad in some cases — the interaction of Australian Super with Indonesian tax obligations should be reviewed with a specialist. Many Australian multinationals in Indonesia provide expat tax equalisation — ensuring the employee's net pay is equivalent to what they would earn in Australia.
