From todays Channel 7 News:

And in one more bit of House news, the Customs and Excise Duties Amendment Bill was passed in the House today. This implements the CARICOM external tariff and will lower the tax on beer imported from the Caribbean make it so that Heineken brewed in St. Lucia and Belikin brewed in Belize should sell for about the same price. Red Stripe and Carib which come from more developed CARCIOM countries will be considerably cheaper, but slightly more expensive than Belikin. The law goes into effect on August first.
