As of December 1, 2017, Australia introduced some big changes to its cervical cancer screening program. The outdated pap test has been replaced with a new HPV test, and intervals between testing have extended from once every two years to testing once every five years. There is also a new recommended age to begin testing. Australian women were previously encouraged to begin screening at age 18, but women are now advised to begin screening at age 25.
The reason for the changes is due to the improved accuracy of the HPV test. Experts claim that HPV testing is more accurate than the pap test, and therefore does not need to be done as often (source).
