What is the effect of CPI on commercial property owners and tenants?

The CPI figure can have a significant impact on commercial property owners and tenants where a lease includes a CPI-based annual rent review.

Many commercial property leases include an annual increase linked to CPI. For Brisbane and Gold Coast properties, this may be based on the Brisbane All Groups CPI figure, depending on the specific wording of the lease.

For example, where a lease provides for an annual rent increase based on the annual Brisbane CPI and the applicable figure is 4.1%, the rent may increase by 4.1% at the relevant review date.

It is important to check the specific rent review clause in the lease, as leases can contain different mechanisms, including fixed percentage increases, CPI increases, market reviews or combinations of these.

What if the CPI data is released after the set annual review date?

Our commercial property managers monitor important milestones in your lease, including rent review dates.

It can be a complicated process as there are occasions when the annual rent review date occurs before the applicable CPI figure has been released by the ABS. Depending on the wording of the lease, the rent increase may need to be calculated once the relevant CPI figure becomes available and backdated to the applicable review date.

The timing and calculation will depend on the specific rent review clause contained in the lease.

What is CPI?

The Consumer Price Index (CPI) is a measure of the change in prices of a basket of goods and services purchased by households. It is calculated by the Australian Bureau of Statistics (ABS) and is used as a measure of inflation.

The CPI is published for Australia's capital cities, including Brisbane.

How is CPI calculated?

The CPI is calculated by using a weighting system to assign different weights to different goods and services. The weighting system is based on the amount of money that households typically spend on each good or service.
