How do I check flood maps for a Melbourne rental address?

1Why should I check the full address before signing?

For a Melbourne rental, check the full property address and land boundary; a suburb name or apartment floor does not establish the property's flood exposure.

Two homes in the same suburb may have different ground levels, entrances and underground spaces. Collect the street number, street name, suburb, postcode and unit number. If a government map identifies the land parcel, its pin is not the location of your bedroom.

The purpose is to identify questions, rather than assign a safety score. Use official layers to inform enquiries to the rental provider and relevant authority. This guide does not rank flood-free suburbs or assess whether a particular address is suitable to sign for.

2Where do I find the Flood Risk Rating Tool and VicPlan?

As checked on 9 Nov 2026, DTP provides an address-searchable flood-tool entry point; VicPlan separately displays property boundaries and planning layers.

Start at DTP's flood-risk reforms page, find Flood risk rating tool and follow Launch map. DTP describes address search and says a Flood Risk Rating will be included when the new provisions are applied. Do not assume every address already has a rating.

For planning information, use the official map linked from Using VicPlan. Select a suggested address and check the highlighted property and information panel. Refine a duplicated street name with suburb and postcode; an empty search result is not a flood-risk finding.

Record the date, tool, matched address, property boundary, active layers and legend. If the map only identifies the street address, separately record the proposed unit and floor. Include that context in enquiries rather than sending an unlabelled coloured map.

3How do I find flood-related layers in VicPlan?

VicPlan layer names and locations change, so look in the layer list for layers labelled flood or AEP, then check the legend and the property boundary.

VicPlan is a planning map, and flood-related layers sit in its layer list, usually with flood or AEP in the name. The exact name and folder are whatever the official guidance and interface show on the day, and this guide does not fix them. Planning zones and overlays are different information, so the absence of an item in a planning section does not finish the flood enquiry.

Interface labels may change, so follow the current official instructions. Zoom to see the entire property, ensure the layer and legend are loaded, and examine how the mapped area intersects it. A failed load, an inactive layer or an unsuitable scale is not a meaningful result.

4Does 1% AEP mean a flood happens only once in a century?

A 1% AEP is a one-per-cent chance of a flood of that size being equalled or exceeded in any year, not a fixed once-a-century schedule.

The Victorian Government's Know your risk page explains that flood occurrence and intervals are unpredictable. A probability layer is not a promise of a flood-free remainder of the century after an event, or a live water-level forecast.

Read the full layer title, legend and explanatory information together. The percentage defines the scenario; it does not establish the chance of water entering your apartment, a loss amount or insurance coverage. Those conclusions require further property-specific evidence.

5Does an unmarked map prove the basement car park is safe?

The official map is general reference information and does not consider individual circumstances; an unmarked map does not prove that a unit, entrance or basement is safe.

Know your risk warns that its address pin represents the property centre and results are based on that point. Zoom in to examine the whole boundary. Information is updated as flood studies are completed, so a point-search screenshot is not permanent certification.

Living on a higher floor does not establish that access, services, parking or storage are unaffected. Conversely, a mapped area does not prove that a particular unit will flood. The building arrangement and relevant authority's information are needed to understand the practical implications.

6What should I ask the rental provider after checking the map?

Use the address search to ask separately about the unit, entrances, basement parking and storage, keeping location-specific replies about water entry and remedial work.

Ask what water-entry events the provider knows about, where and when they occurred, what work followed and which records are available. Locate your actual parking space and storage area. Distinguish no records available from a statement that no event occurred.

Observe and record rather than assessing drainage engineering or entering restricted spaces. Note the unit floor, common entrances and parking ramp, retaining them with the map and written replies. See the inspection checklist for other viewing checks.

7Where can I verify unclear or conflicting flood information?

For unclear Victorian address information, seek clarification from the local council or Catchment Management Authority; one screenshot cannot establish property-specific consequences.

Know your risk lists the council and Catchment Management Authority for an address, and recommends the latter for current flood-extent and property-impact information. Use the authority identified for the address rather than guessing from the suburb name.

If tools appear to disagree, ask about the difference using the same address, dates and layer names. The government expressly says the Know your risk map is not for planning or emergency use. A pre-signing search does not replace current official emergency information.
