From Hard Rubbish to Hard Savings: How It Works
For first home buyers, every dollar saved independently reduces the time needed to reach a 10% or 20% deposit threshold. At the 20% mark, buyers avoid Lenders Mortgage Insurance (LMI), which can add a substantial cost to the total loan. Even small consistent contributions to a deposit fund — whether from kerbside reselling or any supplementary income — shorten the savings timeline and reduce the total cost of entry. The APF guide on first home buyers covers deposit strategies, LMI thresholds, and government scheme eligibility in detail.
Younger Australians have long sought supplementary income streams — overtime, second jobs, and parental gifts — to bridge the deposit gap. The kerbside reselling trend is simply a contemporary version of that same improvisation, shaped by the platforms and logistics available to a generation that grew up selling online. What makes it notable is the scale at which some individuals are operating, and the deliberateness with which proceeds are directed toward property savings rather than discretionary spending.

Why the Deposit Problem Is So Acute in 2026
The deposit challenge facing Gen Z buyers in 2026 is the cumulative product of a decade of price growth, elevated construction costs, and a rate environment that has kept borrowing capacity compressed. Lenders apply APRA's serviceability buffer on top of already elevated mortgage rates, requiring applicants to demonstrate they can service a loan at a rate materially above the offered rate — a test that squeezes maximum borrowing capacity even for buyers with stable incomes and strong savings histories.
The serviceability buffer doesn't just affect how much buyers can borrow — it affects the deposit size required to make a purchase viable. A buyer with a given income who can only borrow a certain amount must make up the difference with a larger deposit if they want to buy in their target area. In markets where prices have not corrected significantly despite higher rates, that arithmetic is unforgiving. First home buyers who cannot access the Bank of Mum and Dad — itself increasingly stretched — are left to generate deposit savings from whatever legitimate sources are available.
Government schemes including the First Home Guarantee, the Help to Buy shared equity scheme, and state-based stamp duty concessions offer partial relief, but places are limited and income caps exclude many urban workers in higher-cost cities. For buyers who don't qualify or miss out in a given round, the only alternative is to save harder, wait longer, or look further from the city. Kerbside reselling sits within a broader pattern of Gen Z improvisation in response to structural market conditions that government policy has only partially addressed.
When a generation starts treating council clean-up collections as a legitimate savings strategy, it signals that the deposit gap has widened beyond what conventional wage growth and standard savings rates can reliably bridge within a reasonable timeframe — a structural challenge, not a personal failure.
Crypto, Alternative Assets, and the Deposit Equation
Kerbside reselling is one of several unconventional deposit strategies gaining traction among younger Australians. Cryptocurrency has also attracted attention as a potential accelerator for deposit savings, given the asymmetric returns some digital assets have delivered over multi-year holding periods. However, the volatility of crypto markets means that savings held in digital assets can fall sharply precisely when a buyer needs to convert them — a risk that bank-based savings products don't carry. The APF guide on Bitcoin, Crypto and Australian Property covers the practical and tax implications of using crypto proceeds in a property purchase, including how the ATO treats crypto disposals as capital gains events.
The tax treatment of kerbside reselling income is also worth noting. The ATO distinguishes between hobby income and business income. Where reselling is conducted regularly and with a profit motive — as is the case for buyers treating it as a structured side income — there is an argument that proceeds are assessable income. Buyers in this situation should keep records and, if the activity is material, seek advice. This connects to broader property finance discipline: deposit savings strategies work best when they are tax-aware from the outset. The Australian Property Tax Guide outlines how different income types affect mortgage serviceability assessments and tax obligations.
Practical Implications for First Home Buyers Building a Deposit
The kerbside reselling trend offers a practical lesson beyond its novelty: consistent, disciplined supplementary income — regardless of its source — materially accelerates the deposit timeline. Buyers who treat every supplementary income stream as non-negotiable savings rather than discretionary spending will reach their deposit target faster than those who treat the same income as spending money. The structural challenge is real, but the behavioural response matters.
First home buyers should also consider how supplementary income is documented when applying for a mortgage. Lenders typically require two years of evidence for self-employment or irregular income to include it in serviceability assessments. Reselling income that is not formally declared or documented may not be countable as income for lending purposes — though the savings it generates are of course real. Buyers building a deposit through side income streams should speak with a mortgage broker early about how their income profile will be assessed and what documentation they should maintain.
Finally, the ingenuity on display in the kerbside trend reinforces that deposit strategies should be multi-pronged. Government schemes, high-interest savings accounts, supplementary income, and disciplined expense reduction can all operate simultaneously. No single approach is sufficient on its own for most buyers in major capitals. The willingness of Gen Z buyers to pursue unconventional avenues is a rational response to a market that has made conventional pathways — save, earn, borrow — increasingly slow to deliver results.
