Electronic Communications Act 2000

A proposal to form a contract made through 1 or more electronic communications that—

is not addressed to 1 or more specific parties; and

is generally accessible to parties making use of information systems, is to be considered as an invitation to make offers, unless it clearly indicates the intention of the party making the proposal to be bound in case of acceptance.

Subsection (1) extends to proposals that make use of interactive applications for the placement of orders through information systems.
