1000 Ringgit

Brunei shifted this denomination to polymer in 1998 — the same year Note Printing Australia began supplying the series — making it one of the higher-value polymer notes in circulation anywhere in the world at the time. Most central banks were still testing polymer on low-denomination, high-turnover notes; issuing it at 1000 Ringgit was an unusually confident move for a small-currency jurisdiction.

The 2006 date places this within the reign of Sultan Hassanal Bolkiah, who has personally overseen every significant redesign of Brunei's currency since independence. The Autoriti Monetari was only formally established in 2011, meaning notes dated before that year were technically issued under the predecessor authority — a detail that affects how the issuer field should be read for pre-2011 pieces in this series.
