Government departments will be cut to 14 from Feb. 1, 2020, down from 18 now, Morrison told reporters in Canberra.
“I want a public service that is focused on the continuity of policy and service delivery,” he added.
Morrison earlier this year told public servants that his government’s policy was not being delivered quickly enough.
Despite trimming the number of government departments, Morrison said he would not cut the number of ministers in his cabinet, negating the need for a reshuffle.
Morrison said the department of education would merge with the department of employment, while agriculture would combine with the environment department.
The department of industry, innovation, and science would merge with energy.
