Maximum of 36 mg per 250 ml serving in beverages. "Australian Food Standards Code: The Australian Food Standards Code restricts the addition of caffeine to kola-type soft drinks, flavoured cordials and flavoured syrups. In these drinks, the total caffeine content must not exceed 145 mg/kg (36 mg/250 ml serve) in the drink as consumed. The Code does not prescribe limits for naturally occurring caffeine in food - for example, tea, coffee and guarana. The caffeine levels in these foods will not normally exceed 100 mg in a standard serving." See www.foodstandards.gov.au. (thanks l) (last updated Nov 22, 2009)

Norwegian law allows a maximum of 32 mg of caffeine per 100 ml of drink. In 2009, energy drinks such as Red Bull became legal in Norway because of trade agreements with Europe. Despite not being part of the European Union (EU), Norway is part of the European Free Trade Association (EFTA) and European Economic Area (EEA). Since the EU changed its regulations to classify Red Bull-like energy drinks as food, members of the EFTA and EEA now must accept EU regulated foods and drinks as trade items.
