What Is a 99-Year Land Lease and How Does It Work in Australia?

What Is a 99-Year Land Lease?

A 99-year land lease — sometimes called a long-term land lease or a perpetual lease — is a formal legal agreement in which a landowner grants a tenant the right to occupy a defined portion of land for a period of up to 99 years.

In return for that right, the tenant pays regular rent to the landowner throughout the term of the lease.

The critical point: the landowner retains full ownership of the land throughout. Nothing is sold. The land title does not change. The landowner simply receives income from a portion of their land in exchange for the documented right of the tenant to occupy it.

Why 99 Years?

Ninety-nine years is a common term for long-term land leases because it is long enough to give the tenant meaningful security — making the arrangement genuinely attractive to tenants — while remaining a finite term that the landowner and their estate can plan around.

Shorter terms (25, 50, or 75 years) can be negotiated, but longer terms generally produce better income for the landowner because tenants are willing to pay a premium for long-term security on their occupancy.

How Is a 99-Year Land Lease Different From a Normal Rental?

A standard residential rental agreement typically has a fixed or periodic term (6 months, 12 months), covers the dwelling, and involves the tenant renting the property from the owner.

A 99-year land lease is fundamentally different:

Standard Rental 99-Year Land Lease
What is leased The dwelling A defined portion of land
Term 6–12 months, periodic Up to 99 years
Income duration Short-term Decades
Tenant security Low Very high
Owner's title Unchanged Unchanged
Registered on title No Yes

The lease is registered as an interest on the land title — protecting the tenant's right to occupy, and protecting the landowner's rights as the owner.

How Does a 99-Year Land Lease Generate Income?

In the context of the Buy My Backyard programme, the income structure works as follows:

  1. A secondary dwelling (granny flat) is built on the defined portion of your backyard land
  2. A 99-year land lease is executed over that portion of land
  3. The tenant occupies the secondary dwelling and pays rent under the lease
  4. You receive that rent as regular income

Because the lease is long-term and formally documented, the income is stable and ongoing — not subject to the short-term uncertainty of standard rental agreements.

Yes. Long-term land leases are a fully recognised legal instrument in all Australian states and territories. They are used extensively in retirement village structures, land lease communities, residential developments, and commercial arrangements across Australia.

The specific legislative framework governing long-term residential land leases varies by state:

  • NSW: Residential (Land Lease) Communities Act 2013 and associated regulations
  • VIC: Residential Tenancies Act 1997 (site agreements provisions)
  • QLD: Manufactured Homes (Residential Parks) Act 2003
  • WA: Residential Parks (Long-stay Tenants) Act 2006
  • SA: Residential Parks Act 2007

Each state has its own framework covering the rights and obligations of landowners and tenants under long-term lease arrangements. Independent legal advice — from a solicitor familiar with your state's legislation — is strongly recommended before entering any long-term lease.

Does a 99-Year Lease Affect My Property Title?

No — not in the way that subdivision does. Your property title is unchanged. You remain the registered owner of your full property throughout the 99-year lease.

The lease is registered as an encumbrance on the title — similar to how an easement (such as a right of way) is recorded. This means anyone doing a title search on your property will see the lease, but your ownership is unaffected. You can still sell the property; the lease transfers to the new owner, who then receives the income.

What Happens to the Lease If I Sell the Property?

The 99-year lease is attached to the land — not to you personally. When you sell the property, the lease transfers to the new owner as part of the land title. The new owner steps into your position as the landowner under the lease and continues to receive the rental income.

This is typically disclosed to prospective buyers through the standard conveyancing process. In many cases, a property with a formal, income-generating secondary dwelling on a long-term lease is an attractive asset for buyers looking for an income-producing property.

Who Typically Uses This Structure?

In the residential context, 99-year land leases are most commonly used in:

  • Land lease communities: Large-scale residential communities where residents own their home but lease the land it sits on
  • Retirement villages: Similar structure, specifically for retirees
  • Secondary dwelling income: Homeowners using the Buy My Backyard model to generate income from unused backyard land

The Buy My Backyard programme applies the same legal structure that has been used in large-scale land lease communities for decades — but makes it accessible to individual homeowners with a single backyard.
