📈 Introduction: A Decade of CPI Shifts Across Australian Cities
Australia’s Consumer Price Index (CPI) shifted dramatically from stable growth to volatile inflation between 2011 and 2024.This dashboard traces living cost changes across major cities, reflecting national trends and local inflationary pressures.
🟢 Setting the Scene (2011–2019): A Decade of Stability
🔻 Plot Twist (2020): COVID-19 Disruption
🔺 Rising Action (2021–2022): The Inflation Surge
🌆 City Spotlight (2023–2024): Regional Differences
- Brisbane reached the highest CPI (142.9) — driven by:
Rental market pressure , Population growth
- Hobart rose sharply — likely from housing
shortages.
- Darwin lagged (CPI: 134.6) — suggesting
milder local inflation.
📊 Climax & Takeaway (2024): A New Inflation Era - By 2025, most cities had CPI above 140 (vs. <100 in 2011) — a 40%+ increase in 14 years.

🔰 Introduction: A Stable Start
Everyday needs like milk, bread, and
vegetables showed no change in the CPI between 2011 and
2019, indicative of a stable cost of living for ten
years. The majority of products were in the neighbourhood of a
CPI index of 100, reflecting the general stability of
the Australian economy.
🚨 Climax: The Inflation Surge Post-2020
After the COVID-19 epidemic, fuel shocks,
housing cost ripple effects, and supply chain
issues caused a rapid increase in CPI values.
🎯 Resolution: Repriced Essentials
The expense of life was redefined by 2025 when all essentials had
increased much above pre-pandemic levels. The ongoing
rise in the cost of food and energy indicates that inflation is
currently a main stress on households.
🟢 Stable Beginning (2011–2019): `
🥛 milk, 🍞 bread, and 🍎 fruit all had CPI values that remained close to 100, indicating a decade of constant costs and stable household budgets.
🔺 Inflation Spike After 2020:
Inflation diverged by item after 2020: - ⛽ Fuel decreased before rising over CPI 130 - 🥦 Vegetables and 🥚 eggs soared to 140–150 due to supply chain pressure - 🍎 Fruit displayed high volatility — influenced by perishability and weather
🎯 Durable Effect (2025):
The cost of all necessities increased by 2025,
although for different reasons.
This change demonstrates how Australia’s cost of living
was transformed by global supply, local
demand, and item perishability.
🟢 Stable Start (2018–2020):
From 2018 to 2020, rent was constant.NT and SA were below ~$350 per
week, whereas ACT and NSW averaged almost $500.There was no inflationary
pressure on housing throughout this time, consistent with Australia’s
overall CPI stability.
🔺 COVID Climax (2020–2022):
Uneven shifts were caused by pandemic disruption: In several places,
early declines in demand resulted in reduced rentals.However, due to a
lack of available housing, returning migrants, and limited rental
vacancies, rents quickly increased by the end of 2021.
🚀 Acceleration Phase (2022–2024):
Rental prices increased nationwide—but not evenly: WA
and QLD rose sharply (60–80% growth),Median rents
jumped from ~$400 to $600+ per week,CPI housing
components rose in parallel, intensifying living costs
🎯 2025 Resolution:
By 2025, rent will become a core inflation driver
across Australia.

🟢 Early Stability (2019–2020):
New and existing tenants faced similar rent rises—under
40%—showing a stable housing market.
🔺 COVID to Recovery (2021–2023):
A clear divide emerged: New tenants faced steep
increases (up to 94%) ,Existing tenants rose
slowly (max ~81%)
🔥 Peak Gap (2023–2024):
The heatmap shows the sharpest differences
here—highlighting rental inequality during housing
shortages.
🎯 2025 Trend:
Slight easing, but the gap remains—new leaseholders
still pay far more than long-term tenants.
