If a firefighter is diagnosed with brain cancer, bladder cancer, kidney cancer, leukemia, or several others, and they have been a firefighter for qualifying periods of service ranging from 5 to 25 years (depending on condition), it is assumed the condition is due to having been a firefighter and firefighters can claim compensation

The presumption applies if the firefighter has been employed for a specific number of years, depending on the type of illness. For example, brain cancer has a 5-year qualifying period, while oesophageal cancer has a 25-year period.

The amendment also ensures that volunteer firefighters who work with the Country Fire Service (CFS) are covered under these protections, provided they meet the attendance and exposure criteria.
