The laws that apply to your electronic transactions will be governed by the applicable jurisdiction. This can be a complicated issue in relation the World Wide Web, particularly regarding contracts where the contract is formed between parties in different countries. Each contract, as well as your website terms and conditions, should specify the applicable law. Your website business can limit the online transactions to contracting with Australian residents only as this will avoid the international jurisdictional problem. However, there may still be State-based issues which you will need to address, so it is important to state the applicable law exactly.
