Apart from the odd exception, Australian general circulation decimal coins are not rare or valuable. It would depend greatly on the condition of the coins and how complete the set is. Some coins of the same denomination have minor differences and/or were minted at different mints. If the coins have been circulated but in good condition, probably not much more than face value since many examples of them will still be in circulation. If the coins are Mint Uncirculated sets produced by the Royal Australian Mint, an average for each year set might work out to about $50 each. If the coins are Proof sets produced by the Royal Australian Mint, an average for each year set might work out to about $60 each.

What can you write about the Australian coin?
Prior to 1910, Australia used the British currency. British coins continued to circulate with Australian coins for many years. The Australian coinage was first introduced in 1910 and included the Threepence, Sixpence, Shilling and Florin. All coins were based on the equivalent British coins and were made from sterling silver. The following year in 1911, the One Penny and Halfpenny coins were introduced, again all based on the equivalent British coins and were made from bronze. Paper money was introduced in 1913. In the early 1960's, it was decided that Australia should have a decimal currency rather than the cumbersome British Imperial style of currency. It was eventually decided that Australia would adopt the Dollar of 100 cents as its currency. The last of the predecimal coins were minted in 1964. On the 14th of February, 1966 the new Australian decimal currency was issued to a well prepared Australian public.
