The arachnology and myriapod collections of the Australian Museum cover the following classes of animals: Arachnida, Diplopoda, Chilopoda, Onychophora, Pauropoda, Symphyla, and Tardigrada.
The major portion of the arachnology collection consists of spiders (Araneae), followed by harvestmen (Opiliones). The emphasis is on the New South Wales fauna, although there are significant holdings from other states (e.g. Tasmania) and regions.
