No. The currencies are not interchangeable.There used to be some crossover with 10 and 20c coins (when they were similar in size), however since New Zealand changed their 10 c coins from silver to copper, and dramatically reduced the size of the 20 c coin, they are now too different to accept.Many Australian retailers will accept the older NZ 10c and 20c pieces which are still partly in circulation in Australia. Whilst it is not "legal tender", it is such a small denomination and so similar in size (but not design) to the Australian 10c piece that some retailers are not bothered by the occasional NZ 10c piece. Others, however, will (correctly) reject the coin, as they cannot bank it or legally use it themselves.

The Superb Lyrebird is on the Australian 10c coin because it is particularly unique to Australia.

A torch signifying Liberty, with an olive branch on the left signifying Peace, and an oak branch on the right, signifying Strength and Independence. Given that this question is in the "Australian birds" category, it is assumed that the question refers to an Australian 10c coin. On the back of the 10c coin is the unique Australian bird known as the Superb Lyrebird. It is known for its amazing ability to mimic a huge variety of sounds.
