The wide variety of reptile species at the Park includes snakes, lizards (such as Komodo dragons), turtles, tortoises, tuataras, American alligators and crocodiles.

In addition, the Park features Australian mammals such as kangaroos, wallabies, koalas, platypuses, Tasmanian devils, bare-nosed wombat, quokkas, echidnas, and dingoes.

The park is heavily involved in snake and spider venom collection for use in the production of antivenom and is credited for saving the lives of thousands.

Worrell begins his snake venom milking work to contribute to the anti-venom manufacturing by the Commonwealth Serum Laboratories.

1970 – The Park begins providing funnel-web spider venom to Seqiris (formerly bioCSL) in the long process of developing an antivenom.

1989 – 4.7-metre-long saltwater crocodile is imported from the Northern Territory on a special jet freighter, and named "Eric" in honour of Worrell.

1992 – John and Robyn Weigel become principal owners of the business, and make the decision to relocate the Park.

1996 – The Australian Reptile Park relocates to Somersby, NSW at a site adjacent to Old Sydney Town, and reopens on 7 September.

2000 – Just past midnight on 17 July, most of the main park building was destroyed when a faulty electrical wiring caused a fire.

2008 – Park Director, John Weigel, is awarded Member of the Order of Australia for his contribution to Australian Tourism and the production of snake and spider antivenoms.

2013 – The Australian Reptile Park remains the sole supplier of terrestrial snake and funnel-web spider venom to Seqiris for the nation's antivenom program.

[9] 2016 – Tim Faulkner and Liz Gabriel named as co-directors alongside John and Robyn Weigel.

List of species Reptiles Amphibians Arachnids Birds Mammals A crocodile named Eric, born in 1947 in Australia's Northern Territory, was featured for many years at the park.

Every year, Eric consumed his own body weight in various animals such as chicken, goat and fish.

Eric the crocodile died on 30 June 2007 from a systemic infection, exacerbated because staff couldn't treat him due to power outages caused by storms in the area.

[14] Since the 1960s, the Australian Reptile Park has been the sole supplier of terrestrial snake venom for the purpose of making antivenom.

Once the venomous snakes have been milked at the Australian Reptile Park, it is then freeze-dried and sent to Seqiris (formally bioCSL) in Melbourne to be made into antivenom.

The dose of antivenom given to a patient varies according to the species responsible for the bite and, when it can be ascertained, the amount of venom injected.

The Australian Reptile Park's venom program houses over 2,000 spiders from baby spiderlings up to full grown adult male specimens; who are milked on a weekly schedule.

Once the funnel-web spiders have been milked at the Australian Reptile Park, the venom is frozen and sent to Seqiris in Melbourne, Victoria.
