Avoid starting a sentence or heading with a number unless it’s a rate, dollar amount, points or tips/reasons/steps, etc.

Thousands, millions and billions can be expressed using k, m, b – and should always be used as such in headings, disclaimers and T&Cs.

BSB numbers include a dash after the first three digits.

Telephone numbers should include spaces.

Number ranges use an en dash without spaces on either side.
