Mining & Resources
The engine room of the economy — BHP, Rio Tinto and Fortescue in the Pilbara, the lithium boom and bust, and how Australia actually taxes what it digs up.
How Australia Taxes Its Mining Boom: Royalties, PRRT and Resource Rent
State royalties, company tax, the PRRT and the failed mining super profits tax – how Australia actually captures value from its resources, and why the new policy focus is downstream processing.
Australia’s Lithium Companies: Inside the Spodumene Boom, Bust and Rebound
Australia mines most of the world’s spodumene. Inside PLS, IGO, Mineral Resources and Liontown – the brutal 2024-25 downturn, the 2026 rebound, and whether Australia can move downstream into refining.
Fortescue’s Story: From Andrew Forrest’s Gamble to the Green Iron Reset
Fortescue built its own railway to break into the Pilbara, reached record 198.4Mt shipments at some of the lowest costs in the world, then bet the company on green hydrogen – and reset in 2025.
Rio Tinto’s Pilbara Machine: How Automation Built the Lowest-Cost Iron Ore System
Rio Tinto runs 18 Pilbara mines, 2,000km of driverless railway and two ports from a control room in Perth. How automation became the cost strategy – and why its hardest problems were social, not technical.
BHP Company Story: How Broken Hill Built the World’s Biggest Miner
From an 1885 silver mine at Broken Hill to a US$26 billion EBITDA global miner: how BHP built its Pilbara iron ore machine, exited petroleum, and rotated its portfolio into copper and potash.
Banking & Financial Services
Four banks, seventy per cent of the market. CBA's deposit moat, Macquarie's two-engine model, the Hayne Royal Commission and the arithmetic behind mortgage profitability.
How Australian Banks Make Money From Mortgages: The Real Economics
Australian banks earn about 2% net interest margin on a A$2.2 trillion mortgage book – and turn it into 13%+ returns on equity. The arithmetic behind it explains almost everything about the sector.
The Hayne Royal Commission: What It Found and What Actually Changed
The 2018 banking Royal Commission found institutions had put short-term profit ahead of honesty. It ended the vertically integrated wealth model – but left Australia’s four-bank market structure intact.
Why Australia Has Only Four Big Banks: Inside the Four Pillars Oligopoly
Four banks hold roughly 70% of Australian banking and three quarters of a A$2.2 trillion mortgage market. How the four pillars policy created that structure – and who is finally taking share.
Macquarie Group: Inside the Millionaires Factory and Its Two-Engine Model
Macquarie earns two-thirds of its income offshore and manages A$941 billion. Inside the annuity versus markets split, the commodities business other banks abandoned, and the profit-share culture.
Commonwealth Bank: How a Government Bank Became Australia’s Most Valuable Company
CBA earns A$10.3 billion a year on a 2.08% net interest margin. Inside the deposit funding moat, the technology spend, the AUSTRAC penalty and the longest-running valuation argument on the ASX.
Energy, LNG & Utilities
Woodside's global LNG build, the Santos takeover that collapsed, AGL's coal transition fight, and why a top LNG exporter forecasts domestic gas shortfalls.
Australia’s Gas Paradox: A Top LNG Exporter Facing Domestic Shortfalls
The ACCC forecasts east coast gas demand of 499 PJ against 488 PJ of supply. How Australia became a major LNG exporter short of its own gas – and what the ADGSM can and cannot do about it.
Origin Energy: The Coal Plant, the LNG Cash Machine and the Software Bet
Origin owns a closing coal plant, an LNG cash machine and a stake in the software platform that may define energy retail. Why AustralianSuper decided that combination was worth more than A$18.7bn.
AGL Energy: How an 1837 Utility Lost Control of Its Own Transition
AGL is Australia’s oldest listed company and its largest generator. In 2022 an activist shareholder defeated its demerger and rewrote its coal closure timetable. What that cost, and what it taught.
Santos: The A$36 Billion Takeover That Collapsed and What Came Next
An ADNOC-led consortium bid A$36.4 billion for Santos, the board agreed, then it collapsed over risk allocation and domestic gas terms. Inside the deal, Barossa, Pikka and the standalone case.
Woodside Energy: How a Perth Gas Company Became a Global LNG Builder
Woodside doubled in size by absorbing BHP’s petroleum arm, then committed to US$17.5bn of US LNG. Inside Scarborough, Louisiana LNG, Sangomar and the sell-down model funding it all.
Retail & Consumer
Woolworths and Coles trading blows inside a duopoly, Wesfarmers' unbeatable Bunnings, the ACCC supermarket inquiry, and how Australian retail survived Amazon.
How Australian Retailers Survived Amazon: JB Hi-Fi, Harvey Norman and Distance
Amazon launched in Australia in 2017 to predictions of retail collapse. JB Hi-Fi answered with the lowest cost base in the category; Harvey Norman answered by being a property company. Both worked.
The ACCC Supermarket Inquiry: What It Found About Australia’s Grocery Duopoly
Twenty recommendations, 20,000 consumer submissions and a Federal Court finding against Coles. What Australia’s supermarket inquiry actually concluded – and the one recommendation that could change the market.
Wesfarmers: The Conglomerate That Works, and Why Bunnings Is Unbeatable
Wesfarmers earns A$4.5 billion of EBIT from hardware, discount retail and chemicals. Why Bunnings has never been successfully challenged, how Kmart rebuilt itself around one brand, and where the risk sits.
Coles Group: The Turnaround, the Demerger and the Year It Beat Woolworths
Wesfarmers bought Coles in the largest takeover in Australian history, fixed it over a decade, then let it go. In FY2025 it beat Woolworths outright – and then gave the advantage straight back.
Woolworths Group: How Australia’s Biggest Grocer Lost a Year
Woolworths sells A$69 billion of groceries a year and still had its worst year in a decade. The arithmetic of a 1.4% price cut in a 5% margin business, and why Coles nearly overtook it.
Superannuation & Investment
A A$4 trillion system that reshaped Australian capital markets. AustralianSuper's scale problem, the Future Fund's mandate, the performance test and Division 296.
Division 296: Australia’s New Tax on Super Balances Above A$3 Million
From 1 July 2026, super earnings attributable to balances above A$3 million face an extra 15%, rising to 25% above A$10 million. What the final law does – and what was dropped along the way.
Australia’s Super Performance Test: The Regulation That Actually Worked
Fail twice and your product closes. How one annual test cleaned up Australia’s default superannuation market, drove a wave of mergers, and why platform products are still the problem.
The Future Fund: Australia’s Sovereign Wealth Fund and Its Mandate Problem
Australia built its sovereign wealth fund from budget surpluses rather than mining royalties. How the Future Fund invests, what the 2024 mandate change did, and why independence is a norm not a guarantee.
Australia’s A$4 Trillion Superannuation System Explained
Compulsory since 1992, now more than A$4 trillion. How Australia’s superannuation system works, why the guarantee rate reached 12%, and which criticisms of it actually hold up.
AustralianSuper: How a Mutual Fund Became Australia’s Most Powerful Investor
A$385 billion, 3.5 million members and offices in London and New York. How an industry fund became Australia’s most powerful investor – and why it says it is now too big for Australia.
Airlines, Transport & Infrastructure
Qantas losing and rebuying public trust, Virgin's collapse-to-relisting, Transurban's fifty-year toll annuity, Aurizon's coal problem and airport economics.
Australian Airports: Why a Runway Is Really a Property Business
Australia monitors airport charges rather than capping them, which made its airports among the world’s most attractive infrastructure assets. Where the money actually comes from, and what Western Sydney changes.
Aurizon: A Regulated Rail Monopoly Built for a Declining Commodity
Aurizon owns an irreplaceable rail network that exists to move coal to port. How regulated access revenue works, and why diversifying a bulk haulage business is far harder than it looks.
Transurban: How a Toll Road Becomes a Fifty-Year Inflation-Linked Annuity
A$3.03 billion of toll revenue and A$178 million of statutory profit. Why toll roads are analysed on free cash rather than earnings, and why the concession contract is the entire investment case.
Virgin Australia: From Administration to ASX Relisting in Five Years
Virgin collapsed in April 2020 and relisted in June 2025 at A$2.90 a share. Inside Bain Capital’s restructuring, the Qatar Airways partnership and whether the turnaround holds as a listed company.
Qantas: How the Flying Kangaroo Lost Australia’s Trust and Bought It Back
Qantas paid A$100 million over ghost flights, lost a High Court case over outsourcing 1,700 jobs, and suffered a major data breach. How it stayed profitable and what the repair actually cost.
Telecom, Media & Digital
Telstra selling the network that made it a monopoly, the Optus failures, the NBN's expensive compromise, media's great unwinding and marketplace economics.
REA Group and Seek: How Australian Publishers Built World-Class Marketplaces
Australian newspapers deliberately cannibalised their print classifieds to build digital ones – and produced two of the world’s best marketplaces. Why the number one platform captures nearly everything.
Australian Media’s Great Unwinding: Selling the Assets That Funded Journalism
Nine sold Domain for A$1.4 billion, News Corp sold Foxtel for A$3.4 billion, and newsrooms shrank. Where Australian media money went and what the News Bargaining Incentive tries to fix.
The NBN: Australia’s Biggest Infrastructure Project and Its Most Expensive Compromise
Australia built a wholesale-only broadband monopoly, then swapped fibre for copper to save money, and is now paying to put the fibre back. The structural reform worked; the execution is the lesson.
Optus: Three Failures in Three Years and What They Cost
A data breach, a national outage and a firewall upgrade that broke emergency calls for 13 hours. How Optus’s failures reshaped Australian privacy law and telecommunications regulation.
Telstra: How a Monopoly Sold Its Network and Bet Everything on Mobile
Telstra was paid to give up the copper network that made it a monopoly. What replaced it: 25 million mobile services, an infrastructure business, and a reliability brand under strain.
Tech Startups & Unicorns
Atlassian selling software without salespeople, Canva at US$42 billion, Afterpay's regulatory gap closing, Airwallex from Melbourne, and why a small market builds global companies.
Why a Country of 27 Million Keeps Producing Global Tech Companies
Every constraint that should have stopped Australia building software companies became a selection mechanism. Why a small market, long distances and scarce capital produced unusually disciplined businesses.
Airwallex: Building a Global Payments Company From Melbourne
Airwallex raised at around US$11 billion in May 2026 with roughly US$1.5 billion in ARR. How a Melbourne startup built regulated payments infrastructure across dozens of jurisdictions.
Afterpay and the End of the BNPL Regulatory Gap
Afterpay listed at A$100 million and sold to Block for around US$29 billion by operating outside consumer credit law. From June 2025 that gap closed – and the sector changed shape.
Canva: How a Rejected Founder Built a US$42 Billion Design Company
Melanie Perkins was rejected by more than a hundred investors. Canva now has 150 million users and around US$4 billion in ARR. The product decision that made it possible, and the AI threat to it.
Atlassian: The Sydney Software Company That Sold Without Salespeople
Atlassian priced Jira low enough that engineers could buy it without procurement, and grew to US$5.22 billion in revenue. Why product-led growth worked, and why it eventually was not enough.
Agribusiness, Wine & Food Exports
Treasury Wine's China cycle, a record beef export year, a2 Milk's daigou collapse, grain handling volatility and the Murray-Darling water market.
Australia’s Water Market: How a River System Became a Tradeable Asset
Australia separated water rights from land title and built one of the world’s most sophisticated water markets. How entitlements and allocations work, and why efficiency and community viability keep colliding.
Australian Grain: The Business Where Rainfall Writes the Annual Report
Silos and port terminals cost the same whether the harvest is huge or nonexistent. Why Australian grain handling has extreme operating leverage, and what the A$101bn to A$73bn forecast means.
The a2 Milk Company: When Your Best Channel Is One You Do Not Control
a2 Milk sold into China through thousands of individual travellers it had no contract with. When borders closed, the channel vanished overnight – and the company could not see it coming.
Australian Beef: A Record Year and the Value of Not Depending on One Market
A record 1,545,784 tonnes exported in 2025 across four large markets, none above 30%. Why beef absorbed the same Chinese trade shock that nearly broke the wine industry.
Treasury Wine Estates: What Happens When One Market Is Your Whole Business
China’s tariffs removed Penfolds’ best market overnight. When they lifted in 2024, the recovery disappointed – and by December 2025 Treasury Wine shares hit an eleven-year low. Why reopening is not recovering.
Property & Construction
Goodman's warehouse-to-data-centre pivot, a housing target missing by 27%, Lendlease's global retreat, REIT cap rates and why builders go broke while busy.
Why Australian Builders Go Broke While Busy
A builder can be fully booked, reporting profit, and insolvent at the same time. The fixed-price contract mechanism behind 2,800 Australian construction failures, and the warning signs that precede them.
Australian REITs Explained: Why Cap Rates Matter More Than Buildings
A building with unchanged rent can lose a fifth of its value because bond yields moved. How cap rates and gearing drive Australian listed property, and why office and industrial diverged so sharply.
Lendlease: When Great Projects Do Not Make a Good Business
Lendlease delivered landmark urban regeneration in London, New York and Milan. The projects were good; the returns were not. Why integrated development, construction and investment failed.
Australia’s Housing Target Is Failing, and Approvals Are Not the Reason
A record 243,864 dwellings under construction and only 43,816 completed in a quarter. Australia is 112,365 homes behind its target, and the bottleneck is capacity to build, not permission to.
Goodman Group: How a Warehouse Developer Became a Data Centre Company
Goodman bought industrial land near cities for warehouses. With AI driving demand and grid capacity the constraint, those same sites became the scarcest input in the data centre build-out.
Healthcare & Biotech
CSL from government laboratory to plasma giant, Cochlear and ResMed as device annuities, pathology logistics, PBS drug pricing and the biotech value gap.
Australia’s Biotech Problem: Great Science, Someone Else’s Profit
Australia discovers and trials, then sells before the value arrives. The gap is not science or talent but the few hundred million dollars a phase three trial costs – and who is willing to fund it.
How Australia Decides What Medicines Cost
A medicine can be approved as safe and effective in Australia and still be unavailable, because a second committee decides whether it is worth the money. How PBS cost-effectiveness assessment works.
Australian Pathology: A Medical Business That Runs on Logistics
A pathology lab processes each extra sample for almost nothing, so volume decides everything. Why the sector consolidated, why collection centre location is contested, and why Medicare sets the price.
Cochlear and ResMed: Why the Device Sale Is Not the Business
A Cochlear implant creates a customer for seventy years. A ResMed device creates a consumables relationship for decades. Why both Australian device companies are annuities rather than manufacturers.
CSL: How a 1916 Government Laboratory Became a Global Plasma Giant
CSL was created in 1916 because Australia was too isolated to import vaccines. It is now a US$15.5 billion plasma therapeutics company – and its moat is a collection network, not a molecule.
Why Australian company stories are worth studying
Australia is a developed economy of roughly 27 million people that has produced globally significant companies in mining, banking, software, medical devices and biotechnology. It has one of the largest pension pools in the world, one of the most concentrated banking and grocery markets, a sophisticated water market, and a regulatory culture that produced both the Hayne Royal Commission and the superannuation performance test.
That combination makes it an unusually useful case study. The constraints are visible — a small domestic market, long distances, concentrated industries, an activist regulatory environment — and the companies that succeeded did so by working within them rather than around them. Each article in this hub takes one company, sector or policy and works through how the money is actually made and where the risk sits.
Every case study runs 2,000 words or more, is grounded in the most recent reported financials, and is written for readers who already understand a balance sheet.
