Modem and Web page hijacking, plus travel and credit-related schemes will be targeted under a plan to fight online fraud.
Australia will join other OECD (Organisation for Economic Cooperation and Development) countries in the fight after members agreed on a new set of guidelines to help nations protect Internet users.
Parliamentary secretary to the treasurer Ian Campbell said the advent of the Internet had increased the opportunities for fraud operators to deceive citizens across the globe.
Campbell said such practices harm legitimate businesses, ultimately reducing consumer confidence in the global marketplace.
"These shady operators are able to escape prosecution in many cases because of the limited ability of law enforcement agencies to pursue them across national borders or share evidence with other national agencies," he said.
