From Akubra to Zinc, the A to Z collection of one dollar coins forms the second Great Aussie Coin Hunt; a partnership between Australia Post and the Royal Australian Mint.

The Ulysses Butterfly and Xanthorrhoea (grass tree) take care of some of the more obscure letters and sit alongside famous brands such as the Victa lawnmower and Milo.

Australia's position in the debate over the origin of Pavlova has also gained wider currency now the meringue-based dish officially has its own coin.

Sydney's Harbour Bridge and Opera House, Melbourne's Queen Victoria Market and Queensland's Great Barrier Reef all feature in a strong showing for the eastern states.

"This year, we are releasing the full alphabet from the start of the hunt but they will be in limited supply, so we encourage those who want the full set to get in quickly to secure their collection of great Aussie memorabilia," Australia Post's Nicole Sheffield said.

The icons that made the cut were selected through internal research at the Royal Australian Mint, CEO Leigh Gordon said.

"There is definitely something for everyone in this coin series and we are delighted to be again working with Australia Post to create a unique and engaging way for all Australians to take a light-hearted look at our way of life," he said.

Collectors can join the hunt by making a purchase at a participating post office and receiving the coins in their change.

For the less adventurous, the entire collection can be purchased in store or online.

A special-edition coloured coin of the Great Barrier Reef can also be randomly found in full set coin tubes.
