The Wealth Trinity, Mastering Australia’s Two Speed Economy
"Note: I am not a financial advisor. The following is a deep dive into wealth-building principles based on my personal strategies, and should not be taken as advice."
Introduction: The Missing Manual
In my last two posts, we’ve looked at the "macro" picture—Adelaide’s critical supply failure and the "outlier" growth we are seeing. We’ve also looked at the "micro" trap—the dangerous reality of entering this market with a 5% deposit, where "access" to a loan doesn't necessarily mean the "ability" to live with it if anything goes wrong.
But if we stop the conversation there, the outlook can feel paralyzing. You are effectively presented with two bad options: miss the boat and get priced out forever, or buy the boat and potentially sink under the weight of 95% leverage.
So, how do you actually win?
The "Great Australian Dream" is often sold as a single step: get the mortgage, pay it off, retire at 65 with enough money to live the rest of your life. But in the volatile, "two-speed" economy of late 2025/early 2026, that single-step strategy is fragile - and it would be insincere of me to promote it as it wildly contrasts my own strategy. Real wealth isn't just about owning a home; it's about understanding and wielding three opposing forces that usually push and pull against each other: Leverage, Diversification, and Compounding.
Most people use only one. The truly wealthy use all three.
Force #1: Leverage (The Accelerator)
Leverage is the concept of using other people's money (the bank's) to amplify your results. It is the primary reason Australians are obsessed with property, and it is the only reason a "regular" income can control a million-dollar asset.
The Math of Leverage
Let’s look at the math using our Adelaide example from previous discussions. If you buy an $880,000 home with a standard 20% deposit, you are putting in $176,000 of your own cash (+buying costs).
If the Adelaide market continues its current trajectory and grows by just 6.2% in a year (the current trend), the asset value increases by roughly $54,560.
Here is where the magic happens.
Asset Return: 6.2%
Cash-on-Cash Return: ~31%
You invested $176,000 to make $54,560. Your money is working five times harder than it would in a savings account earning 6.2%. This is why property investors tolerate the headaches of tenants and toilets—because leverage accelerates wealth creation at a speed that saving wages simply cannot match.
The "Negative Leverage" Trap
However, leverage is an indifferent multiplier. It multiplies losses just as efficiently as gains. As we discussed regarding the "5% Trap," if you enter the market with 95% leverage and the market corrects by just 6%, you aren't just back to zero; you are underwater - a 6% loss has turned into more than a 100% loss of your cash.
Furthermore, leverage has a "holding cost." (interest) In early 2026, with standard variable rates hovering around 5.84% for high-LVR loans, leverage is expensive. It demands to be fed. If your asset grows at 3% but your debt costs 6%, you are starting from behind - this is why I personally avoid rural areas.
The Principle: Use leverage to acquire the asset, but immediately develop a structured plan to get that leverage under control. Leverage is the tool you use to get in the door; it shouldn't be the permanent state of your finances.
Force #2: Diversification (The Shield)
If Leverage is the accelerator, Diversification is the steering wheel (and the airbag).
The average Australian investor is terrifyingly undiversified. They work in a capital city, live in that city, and own an investment property in that city. If the local economy sneezes, their entire net worth catches a cold.
In South Australia, we are facing a "Labor Collision" in 2026 due to the Torrens to Darlington (T2D) project absorbing the workforce. While this might drive up property prices due to supply constraints, it also poses risks to the broader local economy. True diversification protects you from these localised shocks.
My personal diversification happens across three layers: Assets, Property Types, and Income.
1. The "Offset vs. Share Market" Debate
There is a common school of thought that says you should dump all your spare cash into the stock market (ETFs) to diversify away from property. I want to push back on this slightly with some "hard truth" math.
In the current high-rate environment (5.84%), your mortgage offset account is arguably the best "investment" you can make. Why? Because the return is guaranteed and tax-free.
Let's say you are a high-income earner (the "HENRY" demographic). To get $1.00 in your pocket from the share market, you might have to earn $1.60 before tax. Therefore, to beat a guaranteed 5.84% tax-free return in your offset, you would need to find a share market investment paying roughly 9% to 10% per annum consistently. That is a very high hurdle. For most mortgage holders, "maxing out the offset" is the mathematical winner once you factor in the safety element.
My Personal Exception: The $100k Rule.
However, I don't keep everything in the offset. Personally, I maintain a portfolio of roughly $100,000 in diversified ETFs (Exchange Traded Funds).
Why do I do this if the offset return is better? Exposure - I invest in a couple of broad market ETF’s that provide some exposure to US and Global companies, which has recently benefited from the AI boom of 2025, but also should provide a further balancing effect against fluctuating property market prices.
I view my ETF portfolio not as my primary growth engine, but as a Secondary Emergency Fund.
Level 1: Cash in Offset (Primary buffer).
Level 2: $100k in ETFs (The "Break Glass in Case of Emergency" fund).
If something catastrophic happens and I blow through my savings, I can liquidate my shares in 48 hours on my phone. To me, that peace of mind—knowing I have funds completely "outside" the banking mortgage system—is worth the slight "loss" in guaranteed interest efficiency.
2. Property Diversification (Type, Location, & Tenant)
If you are in a position to invest in property, the worst thing you can do is buy a carbon copy of your own home. You need to diversify the source of your returns.
Location Diversification: If you live in Adelaide, buying in Adelaide doubles your risk. Consider markets that operate on different cycles. The East Coast (Sydney/Melbourne) often moves inversely to the smaller capitals. When Sydney is flat, Adelaide often booms (as we are seeing now). By holding assets in different states, (or even suburbs) you smooth out the volatility of your portfolio.
Type Diversification (House vs. Strata):
Houses: Generally offer higher capital growth because the land appreciates. However, they typically have low yields and high maintenance costs.
Units/Townhouses: With the "Quarter Acre Dream" being replaced by medium density, well-located strata titles are becoming essential. They often offer better rental yields and depreciation benefits (tax deductions), which helps cash flow. Being typically cheaper than houses buying a unit might get you access to a suburb that you couldn’t otherwise purchase in.
Tenant Diversification: Your "customer" matters.
Standard Residential: High emotion, 12-month leases.
Student: High yield, high effort.
Short Term Rental: High yield, high effort, high vacancy risk, high policy risk.
Commercial: Businesses pay their own outgoings (council rates, water, insurance) and sign 3-5 year leases. However, vacancies can be longer.
Government/Defense (DHA): With the AUKUS project ramping up, housing leased to Defense Housing Australia offers guaranteed rent (even if vacant) and long leases, though usually with lower capital growth potential.
What am I doing?
I have two short term rentals, two sharehouses, and five long term tenants, across two states and two distinct asset types (houses and townhouses).
3. The Most Overlooked Asset: You (Income Diversification)
Finally, we need to talk about the asset that generates the cash to pay for all of this: You. We often obsess over diversifying our assets but ignore diversifying our income.
Most people have a single point of failure: their salary. In an economy facing a "per capita recession", relying on a single employer is a massive risk. Diversifying your income doesn't just mean driving Uber on weekends. It means:
Skill Stacking: In a market crying out for labor, skills are currency. If you are a tradie, can you get certified for the specific Tier 1 infrastructure work required for T2D? If you are in admin, can you learn AI tools or project management?
Side Hustles: Can you consult? Can you teach? Can you sell a product? Creating a secondary income stream of even $500 a month changes the game. It covers your strata fees. It tops up the offset. It buys the ETFs. Most importantly, it ensures that if your boss calls you into the office for "a quick chat," your world doesn't end.
What am I doing?
I have primary work income (I work casually at a hospital in SA), business income (social coffee), and income through Borrow Well - when you settle a loan with Borrow Well your bank will usually pay somewhere between $4,000 and 7,000 per loan.
Force #3: Compounding (The Engine)
The final force is the one we have the least patience for: Time. We live in a world of crypto-millionaires and overnight success stories. But real wealth is boring. It is the result of doing the right thing, over and over again, for a decade (or more).
The Rule of 72
There is a simple mental math trick called the "Rule of 72." If you divide 72 by your annual return rate, you get the number of years it takes to double your money.
At a 6% return, your money doubles every 12 years.
At a 8% return, it doubles every 9 years.
The key here is that the doubling happens at the end. The growth in year 9 is significantly larger (in dollar terms) than the growth in year 1.
The Cost of Interruption
This is why the "Mortgage Stress" I wrote about in my last post is so dangerous. Compounding is a fragile engine. It requires interruption-free time.
If you leverage too hard (Force 1), ignore diversification (Force 2), and run into cash flow problems, you might be forced to sell your asset in Year 3. If you sell in Year 3, you have likely paid mostly interest and stamp duty. You haven't just lost money; you have killed the compounding engine. You have reset the clock to zero.
The Adelaide Horizon I forecasted that by 2028, Adelaide might hit an "Affordability Ceiling" and growth could slow to 3-4%. Does that mean you should sell in 2028? No. If you are playing the compounding game, a flat market is just a phase you wait through. You are playing for 2035, not 2028. The "winners" in property are rarely the ones who timed the entry perfectly; they are the ones who held on the longest without being forced to sell.
The "Sleep Well" Blueprint
When you combine these three forces, you get a strategy that lets you sleep at night, regardless of what the RBA does next.
Respect Leverage: Use it to get into the market, perhaps even using the 5% scheme if you must, but treat the debt reduction (or offset accumulation) as an emergency. Do not treat your home equity as an ATM for lifestyle purchases.
Embrace Diversification: Don't pour every cent into the mortgage. Build a "Liquidity Moat" using ETFs (my $100k rule) so you are never at the mercy of a bank manager's decision. Diversify your skills or business so you are never at the mercy of a single boss or customer.
Trust Compounding: Ignore the monthly fluctuations. If you have bought a quality asset and you have the cash flow to hold it, time is on your side.
You don't need to be an economist to win this game. You don't need to predict if the "Soft Landing" will turn hard. You just need to build a structure that can survive the volatility, and let the years do the heavy lifting.

It’s also worth mentioning that I’m probably heavily biased - to address this here are four primary resources that partially refute what I’ve written above.
1. AustralianSuper Long-Term Performance Data (Nov 2025)
Refutes: The argument that a mortgage offset account (at ~5.84%) is the "mathematical winner" because finding a 9%+ return in the share market is a "high hurdle."
The Evidence: Data from AustralianSuper (one of the country's largest super funds) demonstrates that the "high hurdle" of 9% is consistently cleared by standard index-based investment options over the long term.
Australian Shares: Returned 9.93% p.a. over the last 10 years.
International Shares: Returned 11.02% p.a. over the last 10 years.
Cash: Returned only 2.03% p.a. over the same 10-year period.
Why it matters: The blog argues that the "guaranteed" return of the offset is superior. However, the primary data shows that over the timeframe required for wealth building (10 years), a diversified share portfolio significantly outperforms the cash/offset rate, even after adjusting for the tax variance.
2. RBA Financial Stability Review (October 2025)
Refutes: The "Leverage is the Accelerator" argument, specifically the safety of entering the market now with the expectation that leverage will "amplify results" positively.
The Evidence: The Reserve Bank of Australia’s formal review explicitly warns that asset valuations are currently "stretched" and that "liquidity mismatches" pose a systemic risk.
The RBA identifies "stretched asset valuations and leverage in global markets" as a primary stability risk.
It warns that a tightening in financial conditions could "limit credit availability," effectively trapping borrowers who relied on leverage to enter the market.
Why it matters: The blog treats leverage as a tool you can "manage." The RBA contradicts this by highlighting that in a "stretched" market, leverage becomes a systemic trap where borrowers cannot refinance or exit, turning the "accelerator" into a mechanism for insolvency.
3. University of Sydney & Victorian Planning Authority Research (via Ray White)
Refutes: The "Adelaide 1-Year Forecast" that the Torrens to Darlington (T2D) project guarantees capital growth or a "hard floor" under prices during the construction phase (2026–2030).
The Evidence: Research indicates that major infrastructure projects often depress or stagnate property prices during the construction phase due to "negative externalities" like noise, dust, and disruption.
Construction Phase Impact: "Temporary disruptions from construction can create localised value dips".
Anticipation Effect: Studies (e.g., John 1998) found that "anticipation of the construction... acted to reduce house prices" due to expectations of disruption.
The "Lag" Reality: Significant price premiums typically only emerge after completion and operation, not during the labor-intensive build phase the blog relies on for its 2026 forecast.
Why it matters: The blog urges readers to buy before the labor collision. The research suggests that buying during the collision (when livability drops) might actually yield a better price, refuting the "closing window" urgency.
4. ATO Taxation Statistics (2022–23)
Refutes: The "Wealth Trinity" premise that property leverage is a reliable wealth engine compared to other asset classes.
The Evidence: The Australian Taxation Office's own data reveals that for the vast majority of investors, leveraged property is a cash-flow drain (a loss), not an income source.
Net Rental Losses: The ATO provides specific line items for "Net rental property loss" because it is the norm for many investors.
Yield Reality: The blog claims leverage "accelerates wealth," but ATO data consistently shows that without significant capital gains (which the RBA warns are "stretched"), the holding costs of property result in annual financial losses that must be subsidized by other income (negative gearing).
Why it matters: This refutes the blog's upbeat "Wealth Trinity" narrative. It confirms that for most Australians, the "Leverage" lever actually removes accessible wealth (cashflow) from their pocket every month, making them entirely dependent on speculative capital growth (which Force #1 and #3 suggest is currently risky).
