What it means
An unsolicited consumer agreement is one negotiated where the seller approached the consumer without invitation, typically door-to-door or by unsolicited phone call, usually for goods or services over $100. The Australian Consumer Law imposes strict rules: the salesperson must disclose their purpose and identity, leave when asked, and provide written terms. The consumer has a 10 business day cooling-off period and the supplier must not supply or take payment during that time for certain agreements.
How it's used
The energy plan he signed on his doorstep was an unsolicited consumer agreement, so he could cancel within 10 business days.
