The coin’s reverse features a large bull shark with smaller bull sharks in the background as well as coloured fish and coral. The design also includes the inscription AUSTRALIA’S BULL SHARK, the 2017 year-date and The Perth Mint’s ‘P’ mintmark.

Each coin is issued as legal tender under the authority of the Government of Tuvalu. The obverse of the coin depicts the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II, the 2017 year-date and the monetary denomination.

The coin is presented in a high-gloss timber display case within a shipper emblazoned with the warning DANGER and is accompanied by a numbered Certificate of Authenticity.
