We believe it sends a strong message to staff and students about being healthy.
ANU has used World No Tobacco Day 2015 to announce it will go smoke free from the middle of July.
The new policy will cover the entire ANU campus in Canberra as well as remote ANU campuses such as the Mt Stromlo Observatory and Kioloa coastal campus near Batemans Bay.
Following extensive consultation with staff and students, ANU will go smoke free from the start of the second semester on July 20, but with a strong focus on support to help staff and students quit the habit.
"The University is announcing our decision to go smoke-free on World No Tobacco Day because we believe it sends a strong message to staff and students about being healthy," said ANU Vice-Chancellor Professor Ian Young AO said.
"The University is committed to providing a safe and healthy campus environment for staff, students, contractors and visitors. We feel this will help to address that."
To help staff and students adjust to the new policy, ANU will also provide support to staff and students who wish to quit smoking.
ANU will pay for QUIT courses for staff and PhD students. Undergraduate students can contact ANUSA for details of how to access QUIT courses.
Information on support programs can be found at http://hr.anu.edu.au/smoke-free or by emailing email@example.com.
Smoking is already prohibited inside ANU buildings and within 10 metres of building entrances.
The new policy prohibits all smoking, including electronic cigarettes, in or around any of the University's campuses.
However, smoking will be allowed in special designated smoking areas around licenced venues and residential colleges.
