Confusing Words

shall vs will

These auxiliary verbs are often confused because they both relate to future actions, but in modern Australian English they have different uses and frequencies.

  • shall — shall' is used to express future intention for first person (I/we) in formal or legal contexts. It is also used in formal questions offering help or politely asking what to do. For example: I shall attend the meeting. Shall we begin the presentation? 'Shall' is rare in modern Australian English.
  • will — will' is used for almost all future purposes in modern Australian English, including intention, prediction, and requests. For example: I will attend the meeting. It will rain tomorrow. The clock will strike at noon. In everyday Australian English, 'will' is the standard choice.

Memory rule: In modern Australian English, use will for almost all future meanings. Use shall only in formal questions (Shall we begin?) or very formal/legal documents.
