Interstate Landlord Portfolios - Managing Insurance Across States

More Australian property investors are building portfolios across state lines. Maybe you started with a unit in Sydney, added a house in Brisbane for the rental yield, and picked up a townhouse in Melbourne. The investment logic makes sense - diversify across markets.

But from an insurance perspective, multi-state portfolios create a set of challenges that single-state investors don’t face. Different stamp duty rates, different natural disaster loadings, different insurer appetites by location, and the admin headache of managing multiple policies with different renewal dates.

At Tank Insurance, we have a couple of specialists who work closely with multi-state landlords. Brady works with a lot of buyers’ agents and real estate agents managing landlord insurance across every state, and Erika - who was previously an account manager at one of Australia’s largest buyers’ agencies - brings experience across both the real estate and insurance sides. Between them, they’ve seen most of the challenges interstate portfolios throw up.

The stamp duty difference

Insurance premiums attract stamp duty, and the rate varies by state. This means the same base premium costs different amounts depending on where the property is located. Rates as at March 2026:

State/Territory	Stamp Duty Rate on General Insurance
NSW	9%
VIC	10% (8% for commercial lines, reducing annually to 0% by 2033)
QLD	9%
WA	10%
SA	11%
TAS	10%
ACT	0% (no stamp duty on general insurance)
NT	10%

For a single property, the stamp duty difference is modest. But across a portfolio of 5-10 properties, it adds up. ACT investors pay no stamp duty on their insurance premiums at all - a genuine cost advantage.

When we quote multi-state portfolios, we show the stamp duty breakdown for each property so you can see exactly what you’re paying and where.

Natural disaster loadings - the hidden cost

This is where the biggest pricing differences appear between states. Properties in areas exposed to cyclone, flood, bushfire, or severe storm carry natural disaster loadings that can dramatically affect the premium.

The biggest impact areas

• North Queensland - cyclone and flood loadings make Townsville, Cairns, and Mackay among the most expensive areas to insure in Australia. According to the ACCC’s monitoring reports, average home insurance premiums in North Queensland sit around $3,000 per year compared to a national average closer to $1,800 - and individual high-risk properties can be significantly higher. Specialist underwriting agencies like Sure Insurance (backed by Steadfast and with QBE providing underwriting capacity for regional Queensland) focus specifically on this market, which tells you something about how different the risk profile is up there.
• Coastal NSW - flood-prone areas along the Northern Rivers (Lismore, Ballina) have seen significant premium increases since the 2022 floods. The Insurance Council of Australia reported the 2022 flood event generated over $6.4 billion in claims, and some Northern Rivers property owners have reported premium increases of 50-200%.
• South East Queensland - Brisbane and Gold Coast have increasing flood and storm loadings
• Rural Victoria and NSW - bushfire-prone areas attract higher premiums, particularly for properties near national parks or grasslands. Properties with higher Bushfire Attack Level (BAL) ratings can face significantly higher premiums or limited insurer appetite
• Coastal WA - cyclone risk in the Pilbara and Kimberley regions

If you’re building an interstate portfolio, the insurance cost of the property’s location is worth factoring into your investment analysis. A high-yield property in a natural disaster zone might cost three times as much to insure as a lower-yield property in a low-risk area.

One insurer or best-of-breed per state?

This is the most common question we get from multi-state landlords. There are two approaches:

Consolidate with one insurer

Pros:

• One renewal date across the whole portfolio
• Simpler administration
• One claims process and one point of contact

Cons:

• No single insurer is the most competitive in every state
• You may be overpaying on some properties to get the convenience of consolidation
• If the insurer has a bad claims experience in one state, it can affect your entire portfolio at renewal

Best-of-breed per state

Pros:

• Most competitive price for each individual property
• Best cover for each property’s specific risks
• Not dependent on a single insurer’s appetite

Cons:

• Multiple renewal dates and policies to manage
• More admin and more invoices
• Claims on different properties go through different insurers

Our recommendation: Use a broker to manage the portfolio regardless of which approach you take. A broker coordinates all the renewals, manages claims across insurers, and can advise on whether consolidation or split policies tends to work better for different portfolio structures.

For most multi-state portfolios, we find a hybrid approach works best - consolidate where one insurer is competitive across multiple properties, but split out properties in high-risk areas where a specialist insurer offers significantly better terms.

Aligning renewal dates

If you’ve bought properties at different times, you’ll have different policy start dates and renewal dates scattered throughout the year. This creates admin headaches and makes it hard to review your portfolio holistically.

The fix: align renewal dates. When you add a new property or switch insurers, your broker can set the policy term so all properties renew at the same time (or close to it). This means:

• One annual review of your entire portfolio
• One round of market shopping across all properties
• One consolidated recommendation from your broker
• Easier budgeting and cash flow planning

There may be a small pro-rata cost to align a mid-term policy, but the long-term administrative benefit is worth it.

State-specific risks to watch for

Each state has insurance quirks that interstate investors should be aware of:

NSW

• Flood mapping has been updated following recent events - check whether your property’s flood risk classification has changed
• The Emergency Services Levy (ESL) is charged as a separate line item on your premium and adds a meaningful percentage on top

VIC

• Victoria’s fire services funding comes through council rates (the Emergency Services and Volunteers Fund), not through your insurance premium - so unlike NSW, there’s no emergency services levy on your policy
• Earthquake risk is higher than most people realise, particularly in regional VIC
• Commercial insurance stamp duty is reducing annually (8% in 2025-26) and being phased out entirely by 2033

QLD

• Cyclone and flood are the dominant cost drivers for North Queensland
• Some insurers won’t quote north of Rockhampton
• Check whether flood is included or excluded in your policy - it varies

WA

• Cyclone risk in the north significantly affects pricing
• Perth and southern WA are generally lower-risk and more affordable to insure

SA

• Highest stamp duty rate (11%) adds to the cost
• Generally moderate risk profile and competitive pricing

TAS

• Stamp duty at 10% puts it in line with VIC, WA, and NT
• Growing investor market with relatively competitive insurance pricing
• Bushfire risk in rural areas

ACT

• No stamp duty on insurance - a genuine cost saving
• Generally low-risk and competitive

How a broker simplifies multi-state portfolios

Managing a multi-state portfolio through direct insurers means separate logins, separate renewal notices, separate claims processes, and no one looking at the portfolio as a whole.

A broker manages the entire portfolio in one place:

• Annual portfolio review - we review every property’s cover, sum insured, and premium at least once a year
• Market shopping - we know which insurers are competitive in which states and for which property types
• Claims coordination - one phone call to us, regardless of which insurer covers which property
• Renewal alignment - we can consolidate renewal dates for easier management
• Sum insured monitoring - we flag properties where the sum insured looks low relative to current rebuild costs

Whether you’ve got 2 properties or 20+, the approach is the same. Brady and Erika treat your portfolio as a whole - not as individual policies scattered across different insurers and renewal dates.

Frequently Asked Questions

Should I use one insurer for all my investment properties?

Not necessarily. Different insurers are competitive in different states. A broker can assess whether consolidating gives you a better deal or whether splitting across insurers gets better pricing per property.

Does stamp duty on insurance vary by state?

Yes. Rates range from 0% in ACT to 11% in SA. This adds a meaningful cost difference across a multi-state portfolio.

Why does landlord insurance cost more in Queensland than Victoria?

North Queensland properties attract cyclone and flood loadings that significantly increase premiums. Coastal QLD properties can pay significantly more than comparable Melbourne properties due to natural disaster risk.
