From 2005 to 2014, Kekovich headed a well-known annual advertising campaign for Meat and Livestock Australia in the lead-up to Australia Day encouraging people to eat more Australian lamb. The advertisements were delivered in the style of Kekovich's deadpan rants, and often made satirically outlandish statements un-Australianism. The first such advertisement drew particular controversy, when he labeled vegetarians as being un-Australian for not eating lamb on Australia Day, provoking outrage from animal rights activists and groups such as the Australian Vegetarian Society; but the Australian Advertising Standards Bureau allowed the ads to remain on the air, ruling them to be satirical, despite viewers' complaints. Many of the subsequent ads have also drawn complaints from viewers, but all have been dismissed by the Bureau. In the Australia Day commercial promoting lamb for the BBQ, which featured Richie Benaud, Kekovich made an appearance along with "Captain Cook", "Ned Kelly", "Burke and Wills", and Ita Buttrose.
