The obverse
The Ian Rank-Broadley portrait era
Ian Rank-Broadley's effigy of Queen Elizabeth II faces right within a broad inscription ring. The monarch, Australia, 2015 date and one-dollar denomination identify the legal-tender obverse.
The 2015 issue
An anniversary issue built from the original
The 2015 standard one-ounce issue occupies a special point in the chronology: it is a new dated mainline coin whose reverse deliberately reuses the inaugural 1990 composition.
The anniversary relationship is visible in the design. The reverse carries the paired date 1990–2015, the P25 mintmark and the familiar kookaburra on a stump. The comparison below places the standard 1990 and 2015 reverses together.
Proofs, high-relief pieces, privy products and other formats are separate releases and are not included in this standard annual entry.

Design story
The inaugural reverse returns with anniversary dating
The 2015 reverse preserves the central bird, stump and foliage relationship of 1990, then changes the surrounding identity with 1990–2015 dating and a P25 mintmark.
Anniversary comparison
1990 and 2015, face to face
The shared bird-and-stump composition shows the anniversary relationship; the paired date and P25 mintmark distinguish the later issue.
The reverse
A twenty-five-year return
Stuart Devlin's kookaburra-on-stump design is paired with the anniversary date and P25 mintmark. The standard coin remains a dated annual issue, not a generic reproduction of the 1990 object.
