The article is a rare investigation into multinational activity in a wealthy resource-based colonial economy toward the end of the first wave of globalization. It challenges the conventional wisdom that multinationals had a limited presence in pre-1914 Australia, where government loans and portfolio investment from Britain into infrastructural and primary industries dominated.

Colonial ties, natural resources, stable institutions, and high incomes all attracted foreign firms.
