You are the second person to ask about an Australian coin that, in theory, should not exist.
Can you provide any more detail about your coin?
See the link below.
There were no Australian (or Western Australian) Pennies minted prior to 1911. An image of Queen Victoria and the inscription VICTORIA DEI GRA BRITT REGINA FID DEF IND IMP (Queen Victoria, by the Grace of God, Queen of the British Territories, Defender of the Faith, Empress of India) or similar, would have appeared on the obverse of any official British coin minted in 1896. What you may have is a Traders token or a medallion. The reverse may have a business name and address on it or, some sort of commemorative inscription.
Your coin is an 1896 British Queen Victoria bronze One Penny coin. The reverse of the coin shows the iconic helmeted figure of the goddess Britannia seated and holding a trident and shield. Britannia personifies Great Britain and has been used on British coins for hundreds of years.
Children had a picture of Queen Victoria in their classroom so that they could pay their respects and do her proud.
The Australian 5 cent coin has an echidna on it?
You are out of luck. Victoria did not become Queen until 1837.
There is a picture of Victoria with her sister on Victoria's twitter. They are hugging a Christmas tree in the photo. Her sister is also on Victoria's keek.
