To add to idiomaddict’s great points, the animals don’t eat exclusively grass. In Australia (assuming based on your instance): “the latest estimate (2017-18) of annual feed use in Australia is 13.58 million tonnes” (SFMCA).
This includes “cereal grains, legume grains, vegetable protein meals, animal protein meals, cereal milling co-products, minerals and vitamins” as per that same source.
I often see people use the deforestation of the Amazon for soy crops as a sort of gotcha for vegans, even though most soybeans are grown for use as animal feed (in the Amazon, mainly cattle). Incidentally, cattle farms are also responsible for much more deforestation in the Amazon than soybeans, but I digress.
I’ll also note that grass-fed beef has often been shown to be as bad (or sometimes worse) for the environment than feedlot beef. It also can’t scale to meet current meat consumption.
in fact, most soy beans are grown for oil, and even what is fed to livestock is mostly the byproduct made by pressing beans for oil. but even beyond that, cattle only eat about 7% of the total global soybean crop.
a soybean is only like 1/5 oil. after we’ve extracted the oil, feeding the meal or cake as it’s variously called to animals is a conservation of resources.

Cattle sure, but if you include poultry and porc that shoots up to around 80% of soy used for feed.
