Country-level figures — Istanbul is not Turkey and Sydney is not Australia, and both cities typically pay above their national average. Gross, before tax: see take-home pay by country for what lands in the account.
Distance
How far is Istanbul from Sydney?
Istanbul is about 14,950 km (9,290 mi) from Sydney in a straight line — roughly 18 h 20 m of nonstop flight time.
Great-circle distance, not a routed itinerary; flight estimate assumes ~850 km/h cruise plus 45 minutes of taxi, climb and descent.
Climate
Is Istanbul warmer than Sydney?
Sydney is the warmer city: January highs average 26°C vs 9°C, and July 17°C vs 29°C. Sydney gets noticeably more sun — about 540 more sunshine hours per year.
| Month | Istanbul | Sydney |
|---|---|---|
| January (high / low) | 9° / 4°C | 26° / 19°C |
| July (high / low) | 29° / 20°C | 17° / 8°C |

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Istanbul | Sydney | Winner |
|---|---|---|---|
| Affordability | 6.8 | 4.5 | Istanbul +2.3 |
| Quality of life | 5.6 | 7.1 | Sydney +1.5 |
| Remote-work friendliness | 4.8 | 4.7 | Istanbul +0.1 |
| Healthcare | 4.8 | 7.5 | Sydney +2.7 |
Each axis is a weighted aggregate of underlying indicators normalized to a 0–10 scale. Weights are explicit and disclosed per axis. The composite is the unweighted mean of the four axes — axes are not collapsed further because the underlying trade-offs (e.g. low cost vs poor air quality) are user-dependent.
Affordability
- Cost-of-living index (weight 60%)36
- Rent index (weight 40%)27
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Istanbul: ((100 − 36)/100 × 0.6 + (100 − 27)/100 × 0.4) × 10 = 6.8.
Istanbul is mid-range on absolute cost. Affordability is reasonable but not its main advantage.
Quality of life
- Safety index (weight 40%)52
- Healthcare index (weight 35%)68
- Air quality index (weight 25%)45
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Istanbul: (52/100 × 0.4 + 68/100 × 0.35 + 45/100 × 0.25) × 10 = 5.6.
Istanbul has a mixed quality profile. Safety: fair; healthcare: good; air: fair. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)40 Mbps
- Effective income tax (lower = better) (weight 30%)12.6%
- Cost-of-living (lower = better) (weight 25%)36
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Istanbul: (min(40/300, 1) × 0.45 + (1 − 0.126) × 0.3 + (100 − 36)/100 × 0.25) × 10 = 4.8.
Istanbul works for remote work but isn't optimized for it: internet 40 Mbps, income tax 13%, cost index 36.
Healthcare
- Healthcare quality index (weight 70%)68
- Healthcare out-of-pocket / month (lower = better) (weight 30%)2301
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Istanbul: (68/100 × 0.7 + max(0, 1 − 2301/500) × 0.3) × 10 = 4.8.
Istanbul has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~2301 TRY/month. Cross-border insurance closes the gap.
Each axis is a weighted aggregate of underlying indicators normalized to a 0–10 scale. Weights are explicit and disclosed per axis. The composite is the unweighted mean of the four axes — axes are not collapsed further because the underlying trade-offs (e.g. low cost vs poor air quality) are user-dependent.
Affordability
- Cost-of-living index (weight 60%)57
- Rent index (weight 40%)53
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Sydney: ((100 − 57)/100 × 0.6 + (100 − 53)/100 × 0.4) × 10 = 4.5.
Sydney is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)62
- Healthcare index (weight 35%)76
- Air quality index (weight 25%)78
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Sydney: (62/100 × 0.4 + 76/100 × 0.35 + 78/100 × 0.25) × 10 = 7.1.
Sydney scores good on safety, good on healthcare and good on air. The composite quality-of-life signal is strong.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)90 Mbps
- Effective income tax (lower = better) (weight 30%)24.9%
- Cost-of-living (lower = better) (weight 25%)57
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Sydney: (min(90/300, 1) × 0.45 + (1 − 0.2493) × 0.3 + (100 − 57)/100 × 0.25) × 10 = 4.7.
Sydney works for remote work but isn't optimized for it: internet 90 Mbps, income tax 25%, cost index 57.
Healthcare
- Healthcare quality index (weight 70%)76
- Healthcare out-of-pocket / month (lower = better) (weight 30%)142
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Sydney: (76/100 × 0.7 + max(0, 1 − 142/500) × 0.3) × 10 = 7.5.
Sydney combines good system quality with a manageable out-of-pocket cost (~142 AUD/month). Travel insurance still recommended for non-residents.
Monthly cost delta: Istanbul vs Sydney
Normalized to TRY at 1 AUD = 34.1061 TRY.
| Category | Istanbul | Sydney | Change |
|---|---|---|---|
| housing | TRY 46,176 | A$3,518 | +160% |
| food | TRY 14,574 | A$662 | +55% |

| leisure | TRY 13,040 | A$425 | +11% |
| healthcare | TRY 2,301 | A$142 | +110% |
Where each city's money goes
Two cities can have the same monthly total but very different shapes — one might burn 50% on housing while the other splits more evenly. The composition matters as much as the headline.
The biggest shape difference is housing: Sydney spends 11.2 percentage points more of its budget on it (67% vs. 55%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Istanbul ↔ Sydney
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Istanbul = 36, Sydney = 57); currency-converted at 1 AUD = 34.1061 TRY. Tax differences are not modeled.
| Istanbul gross | Sydney equivalent |
|---|---|
| TRY 40,000 | A$1,857 |
| TRY 75,000 | A$3,482 |
| TRY 120,000 | A$5,571 |
| Sydney gross | Istanbul equivalent |
|---|---|
| A$40,000 | TRY 861,627 |
| A$75,000 | TRY 1,615,551 |
| A$120,000 | TRY 2,584,882 |
Equivalence here means same cost-of-living purchasing power, not same net take-home. Effective tax rates differ between countries; a salary equivalent on cost can still net more or less depending on the destination's tax regime. Use the calculator for tax-adjusted figures at a specific lifestyle tier.

Remote work logistics
Time zones and language: Istanbul vs Sydney
Istanbul (Europe/Istanbul) and Sydney (Australia/Sydney) sit 7 hours apart in standard time. A 9-to-5 in one overlaps the other's for 8 hours a day. Note: Sydney observes daylight saving while Istanbul doesn't, so the gap shifts by an hour part of the year.
Official: Turkish · English: Moderate · Local language: Recommended
Turkish is essential outside multinational firms and tourist zones. English is moderate in Levent/Maslak business districts and among younger professionals; bureaucracy is Turkish-only.
Official: English · English: Native-equivalent · Local language: Not needed
English-native. Australian English has its quirks but functionally universal. Some neighborhoods have heavy Mandarin / Arabic / Vietnamese influence.

How this page is calculated
Data sources
- Mundevo per-city dataset. Cost basket, rent index, safety, healthcare, air quality and median internet for both cities. Reference date: 2026-06-10 (Istanbul) and 2026-05-27 (Sydney).
- FX rate. 1 AUD = 34.1061 TRY, used to normalize cost baskets.
- CityScoreCalculator. Four axes (Affordability, Quality of life, Remote work, Healthcare) computed with explicit weights and explanations. See per-axis calculation strings rendered on this page.
- ComparisonService. Per-category cost deltas (housing, food, transport, utilities, leisure, healthcare) normalized to the origin currency.
Update cadence
Data as of . Last reviewed .
Calculation
For each of the four axes we compute an independent 0–10 score using the formulas printed beside each axis. The composite is the unweighted mean of the four axes. The overall winner is the city with the higher composite, unless the margin is under 0.05 points — in which case Istanbul is shown first as a tiebreaker to keep results stable.
Limitations
- Climate is not scored — we don't yet hold a maintained climate dataset, so weather-driven preferences are not modeled.
- Tax differences between cities in the same country are not modeled (Spain and Germany don't have material regional differences for this dataset).
- Indices are population-level. Personal cost varies with neighborhood, employer benefits and family status.
- Quality-of-life axis weights (safety 0.4 / healthcare 0.35 / air 0.25) are editorial defaults — readers with strong preferences should re-weight manually.
