I think there's a misunderstanding here. Isaac Le Maire founded the Austraalse Compagnie to break the VOC monopoly on trade with the East Indies specifically the Spice Islands. The VOC's monopoly covered specifically trade around the Cape of Good Hope and the Strait of Magellan ie the only known (at that time) routes from Atlantic to the East Indies. It was called the Australian Company because he intended to explore the yet unknown lands in the far south for a new passage. It had nothing to do with the settlement of what we know as Australia, the continent/country.
Le Maire's son Jacob and the navigator Willem Schouten succeeded in discovering a new route via the Le Maire Strait between Tierra del Fuego and Staten Land via the Le Maire Strait and around Cape Horn showing that Tierra del Fuego was but an Island and not part of the southern continent (although they incorrectly assumed the Isola de los Estados was part of a southern continent not the small island it actually was). But the VOC didn't believe them and thought they passed through one of the known routes and were thus trading illegally in the East Indies. Their ships and journals were impounded and Isaac died a broken man. But perhaps if they avoided capture and made it back to the Netherlands with a valuable cargo of Spices to finance the company and navigation logs to explain their new route they could have developed a competing company. Investors would be investing in trade with the Spice Islands not colonization of Australia. Of course as the company develops its new proprietary trade route it may setup up small supply posts in Argentina/Patagonia/Tierra del Fuego near where the ships cross from Atlantic to Pacific and then in Australia/New Zealand on the other side of the Pacific but these would only ever be in support of the East Indies trade just as the Cape Colony was, at least initially.
