This is the baby version of the Australian Proof coin set for the year. It contains the circulating denominations from $2 down to 5 cents; some of them are in "baby" versions - the $2, the 50 cents and the 10 cents (one of the very few non-circulating 10c coins issued).
The Mint says about it:
"Celebrates the arrival of your newest bundle of joy with this 2022 Proof Baby Coin Set. This uniquely and cutely numismatic set reimagines three of Australia’s distinct circulating coins in a gorgeous baby theme.
The shy lyrebird on the 10c coin is now a winky-wonky marionette puppet, while the 50c coat of arms has been given a riotous party makeover with plush roo and emu. Finally, the $2 coin shows an adorable Indigenous baby, looking with giggling wonder at a cute star mobile. Altogether, they create a unique and engaging year set that celebrates the arrival of a new baby, the wonders of a child’s imagination and the simple joys of collecting."
