Tweaking A Victorian Permit: Secondary Consent Or A Section 72 Amendment?

A small change to approved Victorian plans can be a quick secondary consent or a full permit amendment. Choosing the wrong route costs money, notice and time.

Victoria Permits: Secondary consent is fast β€” until it is challenged

Victoria is good at letting you change your mind. The question is how much of the permit you reopen when you do. A small change to endorsed plans β€” a slightly different driveway crossover, a relocated window, a revised roof form β€” can be dealt with cheaply under a condition. Treat it as the wrong kind of change and you are into a section 72 amendment with notice, referrals and a program hit.

For a Think Property Club student, this is a sequencing decision rather than a paperwork one. Get it right and the builder never stops. Get it wrong and an objector, or a council officer on a bad day, stops a project that was three weeks from practical completion.

The deal question

You hold a Victorian permit and the design has to move. Can I use the consent mechanism already sitting in my permit conditions, or must I amend the permit itself? And if I must amend it, what does that cost me in time and exposure?

The checks a student would run

The order and reasoning behind the checks

Start with the condition wording because it decides whether secondary consent is even on the table. Then diff the plans, because the scale of the change decides the route. Then test the four principles, because council applies them and the Tribunal has endorsed them. Only then look at program and review risk, because by that point you know which process you are pricing.

The trap or expensive mistake

The trap is treating secondary consent as a fast lane with no consequences. Planning Victoria's Guide to Victoria's planning system warns explicitly that responsible authorities need to consider secondary consent carefully, because if it is later found to be inappropriate or inconsistent with the permit an affected person may ask for the permit to be amended under section 87. A cheap consent that gets overturned is the most expensive option on the list.

The mirror-image trap is over-lodging. Councils such as Melbourne and Manningham publish guidance for both routes, and a developer who lodges a section 72 amendment for a genuinely minor change pays for notice, referrals and a longer assessment, and creates a fresh avenue for third parties to have a say on a change that would otherwise have passed quietly.

What the rule actually means

A section 72 amendment is an application to amend a permit, including any approved plans, drawings or other documents, and it follows the same process as a permit application with the same notice and referral requirements. What makes it tolerable is scope: the assessment focuses only on the amendment and avoids reopening every issue associated with the approved use or development. Secondary consent is different in kind. It is a less formal planning approval available under a permit condition, and the Planning and Environment Act 1987 framework gives applicants review rights to VCAT for both routes, with third parties having review rights on an amendment but no formal right of objection or merits review on a secondary consent. Planning Victoria's Chapter 5 on reviews records the practical deadlines: an objector review must be made within 28 days of the notice of decision, and an applicant review where the permit was refused or conditions are challenged must be made within 60 days.

What the result means for feasibility and the offer

Model the change against a simple illustration: a three-dwelling infill project where the approved plans are revised to move a driveway and alter one faΓ§ade. Secondary consent, if the condition supports it, is an administrative step measured in days to a couple of weeks with no notice and no third-party review. A section 72 amendment brings notice, referral, a longer assessment and, where an objector is engaged, a possible VCAT review that runs into months.

The cost difference is rarely the fee; it is the delay and the risk of the permit condition changing. Add a line to your contingency for program delay of four to eight weeks per amendment round, and treat any third-party exposure as a probability, not an exception. Where the change is material to the value of the project, the honest answer may be a fresh permit application or a redesign that stays inside the existing permit.

The Think Property Club lesson

Ask which permission the change actually requires, and write down the evidence for that answer before lodging. That is the same discipline students apply to feasibility: define the question, run the checks in order, and make a decision you can defend in a document rather than a feeling.

Frequently asked questions

How do I know if my Victorian change can go through secondary consent?

Look at the permit condition first. Secondary consent is only available where a condition says the plans must not be altered without the written consent of the responsible authority, or that something must be done to the satisfaction of the responsible authority. Then apply the Westpoint principles: the change must not transform the proposal, must not authorise something requiring a fresh permit under the scheme, must not be of consequence to the purpose of the planning control, and must not be contrary to a specific permit condition.

What is the practical difference between secondary consent and a section 72 amendment?

A section 72 amendment is assessed like a permit application, with the same notice and referral requirements, although the assessment focuses only on the amendment rather than reopening the approved use or development. Secondary consent is a less formal consent given under a condition, and there is no formal third-party objection or merits review right. The trade-off is scope: if the change is beyond the condition, you cannot buy the speed by using it anyway.

Can I lose the ability to use secondary consent after the fact?

Yes. Victoria's guide warns that if a secondary consent is later found to be inappropriate or inconsistent with the permit, an affected person may seek to have the permit amended under section 87. That is a genuine program risk, so the safe test is whether a reasonable planning decision would stand up, not whether the council officer agreed at the time.

Who can appeal an amended permit in Victoria?

The same review rights exist for an amendment as for a permit application. An applicant can seek review of a refusal or of conditions at VCAT, generally within 60 days of notice of the decision, and relevant third parties can seek review of a decision to grant an amendment, generally within 28 days. A recommending referral authority may also seek review where its recommended condition was not included.

What should I check before lodging either application?

Read the exact wording of the condition you intend to rely on, compare the current endorsed plans against what you now want, confirm the responsible authority's own practice for that type of change, and check whether any planning provision introduced since the permit now requires a fresh permission. If the answer is yes, neither route avoids it.
