Cornubia is the highest-income suburb in the Logan LGA and prices reflect that. A significant share of purchases fall above Queensland's $700,000 zero transfer duty threshold, and some sit above the $799,999 ceiling for any concession at all. The Australian Government 5% Deposit Scheme still applies where the property falls within the applicable cap, and the LMI it removes at these price points is substantial.

Cornubia sits in the 4130 postcode alongside Carbrook and Shailer Park, bordering the Redland City boundary and close to the Cornubia Forest Park. At the 2021 Census Cornubia had 7,810 residents with a median age of 40 and a median weekly household income of $2,348, the highest in Logan. Housing is predominantly large detached homes on generous, often leafy blocks.

Stamp duty at the top of the range

Established homes under $700,000 attract zero transfer duty under Queensland's First Home Concession, with a partial concession to $799,999 and a maximum saving of $24,525. Above $800,000 no first home concession applies and full transfer duty is payable, which is a real cost at Cornubia price points and needs to be in your budget from the outset. Run the figure with our stamp duty calculator.

The scheme price cap becomes a live issue

Unlike most Logan suburbs, Cornubia is where the Australian Government 5% Deposit Scheme's property price cap actually binds. Plenty of local stock sits above it. Check the cap against the specific property before you rely on the scheme, because assuming eligibility and discovering otherwise late in a purchase is an expensive mistake. See the scheme explained.

If the scheme does not apply

Where the scheme is unavailable, the alternatives are a larger deposit, paying LMI, a family guarantee, or a professional LMI waiver if your occupation qualifies. At Cornubia loan sizes LMI is a significant sum, so this is worth working through properly rather than accepting the default. See avoiding LMI, guarantor home loans and professional lending.

Realistic expectations

Cornubia is not an entry-level suburb, and most first home buyers here are couples with strong combined incomes rather than single applicants. Get a real borrowing figure before you start looking. See pre-approval.

Cornubia investment purchases are firmly growth plays. With the highest entry prices in Logan against rents that remain regional, gross yields here are the lowest in the LGA, so serviceability rests almost entirely on your own income rather than the projected rent. The compensation is a stable, high-quality tenant base and reliable long-term capital performance.

Demand is supported by the suburb's position on the Redland boundary, proximity to the Logan Hyperdome and M1, and the amenity of Cornubia Forest Park.

Negative gearing is the practical reality

At Cornubia price points, rent will rarely cover repayments, so most local investment purchases run at a cashflow deficit funded from salary. Lenders assess that shortfall against your income, which means your borrowing capacity, not the property, is the binding constraint. This is a legitimate strategy for high-income buyers seeking capital growth and tax outcomes, but it needs to be a deliberate choice rather than a surprise. Speak to your accountant about the tax position alongside the credit advice.

Investment loan assessment

Lenders weigh your income, projected rent, existing commitments and portfolio position, commonly accepting 70% to 80% of the appraised rent. Cornubia's established family homes attract quality long-term tenants with low vacancy. See our investment loan page and compare with higher-yield Logan suburbs.

Larger and semi-rural lots

Parts of Cornubia run to larger holdings. Above roughly 2 hectares most lenders apply rural residential policy, reducing maximum LVRs and valuing excess land conservatively. Confirm the position on the specific lot before you commit.

Extension and renovation

Established homes on good land make extension a common value-add. Structural work is usually funded as a construction loan drawn in stages rather than a straight equity release. See renovation lending.

Refinancing a Cornubia home loan is most often worthwhile when a fixed rate is ending, when accumulated equity opens up an investment purchase, or when household circumstances change. With a median age of 40 and the largest loan balances in Logan, small differences in rate translate into larger dollar savings here than anywhere else in the LGA.

Here is how each case works in practice.

Rate differences matter more at scale

This is the practical point for Cornubia owners. On a large balance, a difference of a quarter of a percent is worth several thousand dollars a year, and over a remaining loan term the compounding is significant. Where we would sometimes tell a Bethania owner with a small balance that refinancing is not worth the trouble, the arithmetic in Cornubia almost always favours reviewing. See refinancing.

Your fixed rate is ending

The revert rate at the end of a fixed term is rarely a lender's sharpest offer, and on a Cornubia balance the gap between revert and market can be worth a great deal. Start two to three months before expiry. See fixed rates ending.

You are equity rich

Long tenure and high values mean many Cornubia owners hold very substantial equity. Releasing it can fund an investment purchase, a renovation, or a child's deposit. Structure matters, since cross-securitising properties with one lender restricts your options later. See accessing equity and using equity to buy again.

Helping children into the market

Cornubia parents frequently act as guarantors for children buying in more affordable Logan suburbs. A guarantee uses your equity without requiring cash, but it carries real obligations and should be structured to limit exposure. See guarantor home loans.

Retirement and loan term

Older borrowers face exit strategy questions on longer terms, and lenders vary in how they handle applicants approaching retirement. See home loans for retirees.

Yes, and Cornubia has the highest concentration of complex borrower structures in the Logan LGA. Business owners, professionals, trust and company structures, and self-managed super funds all appear more often here than elsewhere, and the assessment approach differs substantially from a straightforward salaried application.

At the 2021 Census Cornubia recorded a median weekly personal income of $918 and a household income of $2,348, both the highest or near-highest in Logan.

Self-employed and business owners

Full-doc assessment needs two years of returns and financials. Add-backs are where the real difference lies: depreciation, one-off expenses, additional superannuation contributions, non-recurring costs and interest on debts being refinanced can often be added back to assessable income. At Cornubia loan sizes, a lender with a broader add-back policy can change your borrowing capacity by hundreds of thousands. See self-employed home loans.

Trusts, companies and complex structures

Borrowing through a discretionary trust, a company, or with multiple entities in the income chain narrows the lender field considerably. Some lenders handle trust structures routinely, others require guarantees from every beneficiary, and a few decline outright. This is where broker knowledge of individual lender policy matters most. See SMSF property loans.

Professional LMI waivers and high income lending

Several lenders waive LMI or extend higher maximum LVRs to specific professions, and at Cornubia loan sizes that waiver can be worth a very large sum. Eligible occupation lists differ considerably between lenders. See professionals, doctors, lawyers and high income earners.

Alt-doc at higher loan sizes

Alt-doc lending is available but tightens as loan size increases, with lower maximum LVRs at larger balances. See alt-doc lending.

At the 2021 Census, Cornubia had 7,810 residents with a median age of 40, living at an average of 2.9 people per household. Median weekly household income was $2,348, median weekly family income was $2,511, and median weekly personal income was $918.

The highest household income in the Logan LGA

Median household income of $2,348 is the highest of the 45 suburbs Cube Home Loans services, ahead of Greenbank at $2,240 and well clear of the Logan LGA figure of $1,616. Median personal income of $918 is similarly at the top of the range. Cornubia sits at roughly 145% of the LGA household median, which puts it closer to Brisbane's better southside suburbs than to the Logan average.

Established, settled, high tenure

A median age of 40 is six years above the LGA median, and household size of 2.9 matches the average. The combination of high age, high income and conventional household size describes established families in the peak earning years of their careers, many of whom have been in the same home for a long time.

What this means for your application

Cornubia is the suburb where the lending conversation is least about whether you qualify and most about how the loan is structured. At these balances, the variables that matter are add-back policy for business owners, whether a professional LMI waiver applies, whether a trust or company structure narrows the lender field, and how offset and split arrangements are configured over a long term. Small percentage differences translate into large dollar figures, which justifies more attention to structure than most Logan borrowers would need. It is also the suburb where the government schemes designed for first home buyers most often do not apply, because prices exceed the caps. See increasing your borrowing capacity.
