The Charge On The Title: Victoria's GAIC And What It Does To Your Growth-Area Feasibility

GAIC is a one-off charge on growth-area land that can be triggered by the transfer, the subdivision or even the building permit, and it attaches to the title until paid. Price it before you make an offer.

Growth Areas: The charge runs per hectare, so the parcel size drives it

Here is a deal that looks straightforward and is not. A block in a Melbourne growth-area suburb, big enough for a modest subdivision, priced on the basis that the land is the main cost. Then the settlement statement arrives with a line nobody mentioned: a per-hectare charge that has been sitting on the title since before the vendor bought it. That is the growth areas infrastructure contribution, and on larger parcels it is not a rounding error.

The deal question: what is attached to this title?

GAIC is a one-off charge on land in Melbourne's designated growth areas. The State Revenue Office describes four events that can trigger it: a transfer of land in a transaction that attracts land transfer duty, the issuing of a statement of compliance for a plan of subdivision, an application for a building permit where the estimated cost of works exceeds the threshold, or a significant acquisition of a major interest in a landholder that owns affected land. It applies when the first of those events happens after the land enters the contribution area, and it is payable only once.

The critical feature for a buyer is that the liability sits on the title until it is paid. Deferring it does not remove it.

The numbers, and why they matter per hectare

For 2026–27 the rates rose to $122,260 per hectare for type A land and $145,220 per hectare for types B-1, B-2 and C land, up from $118,830 and $141,150 in 2025–26. The excluded-building threshold increased to $1,528,532, and interest on deferred GAIC increased to 5.6063%.

Because the charge is per hectare, the size of the parcel is the driver, not the number of dwellings. A 12-hectare type A holding is 12 times the rate β€” which is precisely why a vendor marketed as "land bank" can look cheap per square metre and expensive per dwelling.

Where the charge does and does not reach

GAIC applies only to land in the contribution area β€” growth-area land zoned for urban use and development in Cardinia, Casey, Hume, Melton, Mitchell, Whittlesea and Wyndham. Generally it does not apply to events involving land under 0.41 hectares, and there are exemptions and no-liability events including certain small subdivisions and duty-exempt transfers. The SRO issues GAIC certificates at no charge, and a certificate shows the status of the land and whether any liability exists. Get one. It costs nothing and it answers the question.

The trap an inexperienced buyer falls into

There are two versions of the same mistake. The first is assuming the charge belongs to someone else because the vendor never paid it β€” but the liability travels with the land, so the new owner is liable, and an existing recording stays on the title until the contribution is fully paid.

The second is assuming the charge is a subdivision cost and forgetting the building permit trigger. If you intend to build rather than subdivide, an application for a building permit above the threshold is itself a GAIC event. The trigger is not always the event you planned for.

How a student would test it on a real site

  1. Confirm the land is inside the contribution area and note the land type: A, B-1, B-2 or C.
  2. Order a GAIC certificate and read the recorded status and any outstanding liability.
  3. Calculate the charge on the actual parcel size at the current financial year rate, and check the rate that will apply at your expected event date.
  4. Decide how it will be funded: paid within three months, deferred with interest, staged against milestones, or provided as works in kind.
  5. Put the full amount, or the interest cost of deferral, into the feasibility before setting your offer.

Then test the sensitivity. If your margin only works when GAIC is deferred at no cost, the deal is not as strong as the spreadsheet suggests.

Cost, timing and feasibility

The rates are indexed annually, so a deal that straddles a 1 July boundary carries a different number than the one you modelled. If you are deferring, remember the interest is calculated daily at the published rate, and the deferred liability stays attached until the next event. And if it is not paid when due, the SRO treats it as a tax default with penalty tax and interest added.

Practical next steps

  1. Order the GAIC certificate before making an offer.
  2. Confirm the land type and the hectare area from a survey, not the agent's estimate.
  3. Price the charge at the current-year rate and again at the next-year rate if your event falls after 30 June.
  4. Model deferral interest as a holding cost, not as a saving.
  5. Read the contract for who bears the liability on settlement and record it in your decision log.

Sources and boundaries

Sources checked 21 September 2026. Jurisdiction and limits: Victoria only, and only for land within the GAIC contribution area. The rates quoted are the 2026–27 rates effective from 1 July 2026; rates, thresholds and the deferred interest rate are indexed or reset each financial year and the contribution area boundaries can change. GAIC does not apply in other states and territories, which have their own infrastructure funding arrangements. Whether GAIC applies to a specific parcel, at what rate, and how it can be paid or deferred can only be confirmed from an SRO GAIC certificate and the applicable determination.

Frequently asked questions

What triggers GAIC?

The first of four events after the land becomes part of the contribution area: a transfer of land in a transaction that attracts land transfer duty, the issuing of a statement of compliance for a plan of subdivision (or certification of a plan under section 35 of the Subdivision Act 1998), an application for a building permit where the estimated cost of works exceeds the threshold, or a significant acquisition of a major interest in a landholder that owns affected land. GAIC is payable only once, at that first event.

What are the current rates?

For 2026–27 the rates are $122,260 per hectare for type A land and $145,220 per hectare for types B-1, B-2 and C land, up from $118,830 and $141,150 in 2025–26. The threshold above which a building permit application is a GAIC event rose to $1,528,532, and interest on deferred GAIC rose to 5.6063%.

Does GAIC apply to every block in a growth-area council?

No. GAIC applies only to land in the contribution area, which is growth-area land zoned for urban use and development in Cardinia, Casey, Hume, Melton, Mitchell, Whittlesea and Wyndham. Generally it does not apply to events involving land under 0.41 hectares, and there are further exemptions and no-liability events, including small subdivisions and certain transfers. A GAIC certificate, which the SRO issues at no charge, shows the status of a specific property.

Who actually pays it?

Usually the person who owns the land when the GAIC event occurs, and if the land is sold or transferred the new owner is liable. For a significant acquisition, both the acquirer and the landholder share the liability. Because the liability is recorded on the title until it is paid, a deferred charge follows the land, not the seller.

What are my options if the liability lands on my project?

You can pay in full within three months of the event, apply to defer until the next GAIC event if you are buying or being transferred the land, seek staged payments aligned with subdivision or development milestones, or enter a work-in-kind agreement providing land or infrastructure instead of cash. The deferral, staged and work-in-kind options each require approval and carry interest or commercial terms, and if GAIC is not paid by the due date it is a tax default with penalty tax and interest.
