An affirmed monarchist, Bishop, along with fellow ministers Nick Minchin and Tony Abbott, supported the "No" campaign leading up to the failed 1999 Republican referendum and on one occasion spoke to Australians for Constitutional Monarchy, warning of the "Seven deadly myths of the republican debate". On 17 July 1991, in response to the infamous debate on the Nine Network's "Midday" television show with host Ray Martin, debating on Australia remaining a constitutional monarchy, in a live televised debate with singer Normie Rowe and radio broadcaster Ron Casey, who ended up physically brawling, Bishop issued a media release which said: "It may well have been High Noon on the "Midday Show" when Ron Casey took a swipe at Normie Rowe but this conduct indicates just how divisive the debate on the Monarchy has become. Not content to see the country on its knees as a result of the recession the Labor Party must be pleased that it is dividing the community on an issue which has absolutely no political relevance."
