Australia's modern coinage has only ever known the face of one monarch - Elizabeth II.
The long-serving queen ascended the throne in 1952. Australia switched to a dollar currency in 1966.
In all the years since, it has been Queen Elizabeth's face on the obverse of every coin in circulation, as well as the now-obsolete $1 bill.

But with the ascent of King Charles III to the throne, that is set to change.
The Royal Mint in Canberra is expected to - at some point - start issuing coins emblazoned with the new monarch's profile.
Nine.com.au has contacted the Mint to ask when this can be expected to happen.

But in the meantime, there are some things we can surmise.
Coins featuring Charles' portrait have already been issued as special edition currency in the UK, including for his 70th birthday.
On these coins, he faces in the same direction as his mother does - that is, to the right.

But traditionally, a new monarch will face the opposite direction to their predecessor on a new minting of coins, meaning currency bearing the face of King Charles, as opposed to Prince Charles, would likely see him facing left.
The Queen also features on Australia's $5 note.
It's less certain whether this will be automatically "updated", with other Australian banknotes likewise featuring late personages of high standing or historical significance.
