Final answer:
Claire will be defined as a retail client under the Corporations Act 2001 unless her investment meets the threshold to be considered a wholesale client, which is not specified but typically requires a significant amount.
Step-by-step explanation:
Under the Corporations Act 2001, Claire would be classified as a retail client unless she invests a certain minimum sum that qualifies her as a wholesale client. The exact threshold amount can vary, but typically it requires a substantial investment amount or stipulations such as the investor having a certificate from a qualified accountant confirming they have a prescribed net wealth or income. The determination of this minimum sum is crucial for investment considerations and understanding the regulatory protections afforded to retail clients as opposed to wholesale clients.
