Sydney edges out Johannesburg on the Mundevo composite, 5.2 to 5.1 out of 10 — a narrow 0.1-point margin across safety, healthcare, air quality and cost.
The composite gap is small enough that one weighted axis can flip the result. Use the per-axis breakdown below to see which city wins your specific priorities — someone optimizing for healthcare can land on a different answer than someone optimizing for affordability.
Run the salary calculator for both cities at your target lifestyle before deciding — Sydney winning on quality doesn't mean the gross-salary requirement also lands in your favor. If you're on a balanced tier, the cost-of-living pages for each city carry the full monthly basket and the gross-salary figure.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Johannesburg | Sydney | Winner |
|---|---|---|---|
| Affordability | 7.0 | 2.2 | Johannesburg +4.8 |
| Quality of life | 4.2 | 7.1 | Sydney +2.9 |
| Remote-work friendliness | 4.9 | 4.2 | Johannesburg +0.7 |
| Healthcare | 4.3 | 7.4 | Sydney +3.1 |
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%)39
- Rent index (weight 40%)16
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Johannesburg: ((100 − 39)/100 × 0.6 + (100 − 16)/100 × 0.4) × 10 = 7.
Johannesburg sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.
Quality of life
- Safety index (weight 40%)18
- Healthcare index (weight 35%)62
- Air quality index (weight 25%)52
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Johannesburg: (18/100 × 0.4 + 62/100 × 0.35 + 52/100 × 0.25) × 10 = 4.2.
Johannesburg has a mixed quality profile. Safety: poor; healthcare: good; air: fair. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)60 Mbps
- Effective income tax (lower = better) (weight 30%)18.0%
- Cost-of-living (lower = better) (weight 25%)39
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Johannesburg: (min(60/300, 1) × 0.45 + (1 − 0.18) × 0.3 + (100 − 39)/100 × 0.25) × 10 = 4.9.
Johannesburg works for remote work but isn't optimized for it: internet 60 Mbps, income tax 18%, cost index 39.
Healthcare
- Healthcare quality index (weight 70%)62
- Healthcare out-of-pocket / month (lower = better) (weight 30%)800
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Johannesburg: (62/100 × 0.7 + max(0, 1 − 800/500) × 0.3) × 10 = 4.3.
Johannesburg has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~800 ZAR/month. Cross-border insurance closes the gap.

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.
Monthly cost delta: Johannesburg vs Sydney
Normalized to ZAR at 1 AUD = 12.1212 ZAR.
| Category | Johannesburg | Sydney | Change |
|---|---|---|---|
| housing | ZAR 9,000 | A$2,800 | +277% |
| food | ZAR 5,000 | A$700 | +70% |
| transport | ZAR 1,100 | A$220 | +142% |
| utilities | ZAR 2,500 | A$220 | +7% |
| leisure | ZAR 4,500 | A$450 | +21% |
| healthcare | ZAR 800 | A$150 | +127% |
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 22.4 percentage points more of its budget on it (62% vs. 39%). If you're sensitive to that category, weight the per-axis scores accordingly.
Buying property
Apartment prices: Johannesburg vs Sydney
Approximate asking prices in EUR per square meter (as of 2025-01), central vs mid-distance neighborhoods.
Buying in central Johannesburg runs about 92% cheaper per square meter (€900/m² vs €11,500/m²).

Getting around
Public transport: Johannesburg vs Sydney
Monthly pass and casual-ride pricing in EUR (as of 2025-01) plus the modes each network runs.
Gautrain (to Pretoria/airport) + Rea Vaya BRT exist, but coverage is thin — most professionals drive or e-hail, and the monthly figure reflects Gautrain-commuter reality.
Single ride: €1.5 · Modes: Bus, Commuter rail
Opal card weekly cap A$50; ferries to Manly and the harbor are the everyday postcard route, not just tourist.
Day pass: €5.4 · Modes: Metro, Tram, Bus, Commuter rail, Ferry
Salary equivalence: Johannesburg ↔ Sydney
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Johannesburg = 39, Sydney = 80); currency-converted at 1 AUD = 12.1212 ZAR. Tax differences are not modeled.
| Johannesburg gross | Sydney equivalent |
|---|---|
| ZAR 40,000 | A$6,769 |
| ZAR 75,000 | A$12,692 |
| ZAR 120,000 | A$20,308 |
| Sydney gross | Johannesburg equivalent |
|---|---|
| A$40,000 | ZAR 236,364 |
| A$75,000 | ZAR 443,182 |
| A$120,000 | ZAR 709,091 |
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: Johannesburg vs Sydney
Johannesburg (Africa/Johannesburg) and Sydney (Australia/Sydney) sit 8 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 Johannesburg doesn't, so the gap shifts by an hour part of the year.
Official: English, Zulu, Afrikaans · English: Native-equivalent · Local language: Not needed
English dominates business and media. The city is massively multilingual (Zulu, Sotho, Afrikaans) but English alone works everywhere that matters for an expat.
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 (Johannesburg) and 2026-05-27 (Sydney).
- FX rate. 1 AUD = 12.1212 ZAR, 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 Johannesburg 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.
