Vienna outscores Sydney by 1.1 points, suggesting substantively different urban conditions rather than marginal preference—the gap reflects real structural differences in livability metrics.
Vienna's 6.3 rating positions it in a different tier than Sydney's 5.2; most cities cluster between these scores, making Vienna's advantage noteworthy but not extreme.
If you're weighing these two cities, examine the specific metric categories where Vienna's lead widened—transportation, housing costs, or safety—to determine if those factors match your priorities.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Sydney | Vienna | Winner |
|---|---|---|---|
| Affordability | 2.2 | 2.1 | Sydney +0.1 |
| Quality of life | 7.1 | 7.9 | Vienna +0.8 |
| Remote-work friendliness | 4.2 | 4.2 | Sydney +0.0 |
| Healthcare | 7.4 | 8.6 | Vienna +1.2 |
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%)80
- Rent index (weight 40%)75
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Sydney: ((100 − 80)/100 × 0.6 + (100 − 75)/100 × 0.4) × 10 = 2.2.
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%)23.0%
- Cost-of-living (lower = better) (weight 25%)80
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 − 0.23) × 0.3 + (100 − 80)/100 × 0.25) × 10 = 4.2.
Sydney works for remote work but isn't optimized for it: internet 90 Mbps, income tax 23%, cost index 80.
Healthcare
- Healthcare quality index (weight 70%)76
- Healthcare out-of-pocket / month (lower = better) (weight 30%)150
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 − 150/500) × 0.3) × 10 = 7.4.
Sydney combines good system quality with a manageable out-of-pocket cost (~150 AUD/month). Travel insurance still recommended for non-residents.

How this is calculated

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 4.7 percentage points more of its budget on it (62% vs. 57%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Sydney ↔ Vienna
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Sydney = 80, Vienna = 84); currency-converted at 1 EUR = 1.6500 AUD. Tax differences are not modeled.
| Sydney gross | Vienna equivalent |
|---|---|
| A$40,000 | €25,455 |
| A$75,000 | €47,727 |
| A$120,000 | €76,364 |
| Vienna gross | Sydney equivalent |
|---|---|
| €40,000 | A$62,857 |
| €75,000 | A$117,857 |
| €120,000 | A$188,571 |
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.

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: 2026-05-27 (Sydney) and 2026-05-28 (Vienna).
- FX rate. 1 EUR = 1.6500 AUD, 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

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 Sydney 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.
