The Commonwealth of Australia did not have its own currency until 1910, well after Federation.
Of the Commonwealth of Australia coins minted for general circulation, the rarest coin would be the 1930 Penny of which there were only 3,000 minted.
The second rarest coin would be the 1923 Halfpenny of which there were only 15,000 minted.
On a scale of 1 to 10, "scarce" is 5, "rare" is 7 and "very rare" is 8. The degree of rarity is calculated by the coin dealer community based on how many times they see a particular coin on the market.
"Rare" and "valuable" should not be confused, a coin can be one or the other or both. A rare coin in poor condition will not be all that valuable.
The following does not include Proof coins.
Halfpenny
Penny
Threepence
Sixpence
Shilling
Florin - (Two Shillings)
These are what are currently considered to be Australia's rarest predecimal coins. It includes only Australian predecimal coins issued from 1910 to 1964 irrespective of where they were minted.
It is unlikely that you will ever see one of these coins outside of a museum or the collection of a very wealthy collector.
The "Pattern" and "Mule" coins should never have left the Mint.
As a general rule, there are no general circulation Australian decimal coins that could be considered to be rare.
Without peeling off a catalogue worth of entries -
Halfpenny - 1916 (mule) and 1923.
Penny - 1937 (pattern), 1920 (no dots) and 1930.
Threepence - 1937 (pattern), 1915 and 1922/1 (overdate).

Florin - 1937 (pattern), 1914H, 1915 and 1932.
No. Although they are no longer in circulation, the Australian 1 and 2 cent coins are still legal tender and are worth 1 and 2 cents respectively. All years of issue were minted in the 10's of millions.
With very few exceptions, Australian 1 and 2 cent coins would have to be in absolute mint condition to have any collector value at all.
1966 1 cent coin in absolute mint condition, minted at the Perth Mint, could get up to $18 AUD. The second whisker on the "sugar glider" will be blunted.
1968 1 cent coin in absolute mint condition, minted at the Melbourne Mint, could get up to $28 AUD. The first whisker on the "sugar glider" will be blunted.
1967 2 cent coin in absolute mint condition, minted at the Perth Mint, could get up to $100 AUD. The first right claw on the "frill-necked lizard" will be blunted and, the designers initials, SD (Stuart Devlin) will be missing.
1968 2 cent coin in absolute mint condition, minted at the Perth Mint, could get up to $100 AUD. The first right claw on the "frill-necked lizard" will be blunted and, the designers initials, SD (Stuart Devlin) will be missing.
NOTE - When referring to the collector value of coins, "rare" and "valuable" do not necessarily go together.
After the abolition of the Guilder, the new most valuable coin would be the 2 Euro coin

There are two Australian 2 cent coins that are considered to be valuable, the 1967 and 1968 coins, both minted at the Perth Mint. What makes them valuable is the missing designers initials (SD) below the lizard and to the left of the front right claw.
