Coolac is a village in the Riverina region of New South Wales, Australia in Gundagai Council.

Since 1986, plans had been drawn-up for the Coolac bypass, with a review of environmental factors report completed in 1997 but construction did not commence until May 2007 with the project opening in August 2009 - Under AusLink.
