You should have your licensing contract reviewed by a lawyer in Australia, and discuss with your Australian lawyer how to best position yourself for taking action if the licensee misappropriates your intellectual property. You would likely want some form of non-compete clause that would prevent them from opening up shop providing an equivalent program for a period of time after the license ends, and you would need any such agreement (and the rest of your contract) to be enforceable under Australian law. You would also want to talk to the Australian lawyer about how you might avail yourself of remedies (injunctive relief, money damages, etc.) in an Australian court with the least expenditure of your own time and money.
