Page "Australian English vocabulary" Paragraph 27

As in British English, the colourless, slightly lemon-flavoured, carbonated drink known in North America and elsewhere under brand names such as Sprite and 7 Up is called lemonade, while the more strongly flavoured drink known as lemonade in North America that is typically made of lemon juice and sugar is sometimes referred to as lemon squash, pub squash, traditional lemonade or club lemon, particularly in carbonated form.
