Islands at equilibrium that are farther from the mainland contain fewer species than nearer islands at equilibrium because farther islands have less colonization.
There is no standard of size that distinguishes islands from continents or from islets.
There is a widely accepted difference between islands and continents in terms of geology. Continents are often considered to be the largest landmass of a particular continental plate; this holds true for Australia, which sits on its own continental lithosphere and tectonic plate
By contrast, islands are usually seen as being extensions of the oceanic crust (e.g. volcanic islands), or as belonging to a continental plate containing a larger landmass (continental islands).
