This "my particular country doesn't import most of its cattle from Brazil" doesn't mean that you're not creating demand and perhaps also influencing the market in a way that someone's beef is. (Collectively, obviously.) The argument sounds similar to "but my country isn't polluting, it's China where we order all our stuff!" And, yeah, animal feed like others already said. It's all not quite as simple as "source? I don't believe I'm part of the problem by creating demand for meat here" coming from the country where the average person contributes the most to global warming

quick search for Beef (carcass weight) per month, international trade with the USA, for Dec. 2021, shows Canada, Mexico as number one and two, but Brazil as a close number three. In that month and year, the trade with Australia is very low.

In addition to what ipqk said, a large amount of deforestation is for growing soy. Approximately 77% of global soy production [2] is used for producing animal feed. It's much more environmentally friendly to just get eat soy directly, rather than eat meat, because animals are very inefficient at converting food they eat to food that people can eat [2].

Denmark imports 1650000 metric tons soya from south america yearly to feed to animals.
