There is no silver in any circulating Australian decimal coin.
No currently circulating Australian coin contains any silver. The only Australian 50 cent coin to contain any silver was the round 1966 coin which had an 80% silver content, about 0.3416 ounces. At today's prices about $10.70 USD.
The first Australian 50 cent coin was issued on the 14th of February, 1966, along with the rest of the initial release of Australian decimal coins and banknotes. The original 1966 50 cent coin was round and had an 80% silver content. Due to steep increases in the proce of silver, somebody figured out that the silver was worth more than 50 cents, so the coin was discontinued. All subsequent 50 cent coins were 12 sided and had no silver in them at all.
today if a 50 cent coin contained the amount of silver and bronze it did in 1966 it would be worth $2.67
The Australian 1966 50 cent coin was the first and last round Australian 50 cent coin produced by the Royal Australian Mint. With the wisdom of hindsight, this coin was a bit of a blunder on the part of the Royal Australian Mint. It was only very slightly larger in size to the Australian 20 cent coin and it had an 80% silver content at a time when the price of silver was increasing rapidly. It took only three of these coins to get one ounce of silver.

The only Australian decimal general circulation coin to contain any silver was the 1966 "round" 50 cent coin. It was made from 80% silver and 20% copper. The price of silver soared in 1966/67 and the silver content became much more valuable than the face value of 50 cents. The coins were soon withdrawn from circulation and replaced in 1969 with the more familiar 12 sided cupro-nickel 50 cent coin.
