The ad, Keeping it Light, was made for the religious group the Bible Society Australia and features two conservative politicians debating the issue of marriage equality.
A number of bars across Australia have dropped the beer brand from their stock because of the partnership, with some even videoing themselves throwing their Coopers Beer stock in the rubbish.
Coopers Beer has now issued an apology for their part in the ad and Director of Corporate Affairs Melanie Cooper says the company supports marriage equality.
âOffence has been taken by our recent involvement, for which we are deeply sorry.â
She went on to say âWe have consequently cancelled the release of our Bible Society commemorative cans and will be taking steps to show further support for our community, including joining Marriage Equality Australia.â
