Proof coins are coins that are prepared on special blanks, struck twice or more to really have great detail, are usually hand-inspected and then placed in special cases for collectors. Proof coins are so shiny that you could use them as a mirror on the parts that don't have a design on them. Usually proof coins sell for much more than their circulation counterparts. Some proofs are struck in precious metal that circulation coins aren't struck in (since 1992, the US has struck both "clad" copper-nickel proofs, and 90% silver proofs).
There were no Australian coins minted prior to 1911. With the possible exception of traders tokens (with the traders business name on them), there were no "Australian" coins minted prior to 1910. The only coins circulating in Australia prior to 1910 were British coins.
