The barrier that Australia has to trade is lack of cooperation among governments within the region (option D)
<h3>What is Australia?</h3>
Australia is a name of a sovereign country in Oceania, whose form of government is the parliamentary federal constitutional monarchy.
This country stands out for being the largest in the continent of Oceania and is also the strongest economy in the region because Oceania is a continent made up of a large number of islands.
In general, the states that make up Oceania do not have strong economies or large export products because their main economic activity is tourism. Due to the above, no economic cooperation agreements have been formed between governments because they do not have products to offer.
