A bilby for Easter

By dcrump | 2 April 2021

The bilby is gaining popularity as an alternative to the Easter Bunny, but have you thought about the origins of the word?

State Library's IYIL2019 Word of the Week: Week 16 - Bilby.

During 2019, State Library celebrated the International Year of Indigenous Languages with a word of the week initiative which showcased a word from the diverse range of Aboriginal and Torres Strait Islander languages across Queensland. To coincide with Easter, the Week 16 word was bilby, from the Yuwaalayaay language of South-West Queensland and North-West NSW – meaning ‘Bilby or Rabbit-eared bandicoot’.

In 2021 leading up to the International Decade of Indigenous Languages, it is timely to revisit the word bilby and explore other language words for this endangered marsupial.

Bilby: Gamilaraay, Yuwaalaraay, Yuwaalayaay Dictionary entry.

The word bilby is sourced from a community dictionary of Yuwaalayaay compiled in 1998 by John Giacon and Ian Sim drawing on the knowledge of language speakers, including Mrs G. Rose, Willie Willis, Greg Fields and Mrs West. Yuwaalayaay was spoken along the Queensland-NSW border, including Goodooga and Walgett and extending into South-West Queensland.

Yuwaalayaay is also known as Yuwalyai, Euahlayi, Yualai, Yualeai, etc. and is closely related to neighbouring languages of Gamilaraay and Yuwaalaraay. Linguistic research indicates Yuwaalayaay is spoken by less than 20 people in the community and classed as critically endangered; it is one of the languages supported by the Walgett Language Program.

The word bilby is derived from 'bilba' which is used in both Yuwaalayaay and the neighboring language Yuwaalaraay.  There is also another word used for the bilby and that is dhuluun.gayaa which is based on dhulu meaning 'stick' and refers to the way that a bilby's tail stands up like a stick when it is running while gayaa is based on gayaay meaning 'sandy country'.

While the word originates from Yuwaalayaay, other groups in Western Queensland also had their own name for the long-eared bandicoot which is found in sandy desert country. Dhanggu was used in the Maranoa-Warrego regions which take in the Bidjara and Gunggari language nations. Thangku was used in Muruwari, while Thalka is the word from Arabana-Wangkangurra languages which straddle the Queensland and South-Australian borders.

Here is a selection of words for bilby from other states:

  • Mankarr (Manjilijarra - Western Australia)
  • Warlpajirri (Warlpiri - Northern Territory)
  • Ninu (Pitjantjatjarra - South Australia)
  • Ahurt (Arrernte - Northern Territory)
  • Dalgyte or Dolgoitch (Noongar - Western Australia)

Did you know that bilbies featured in creation stories as well as depicted in rock art for some Aboriginal groups? 

Today bilbies are considered endangered - the lesser bilby was considered extinct in the 1950's and there is conservation work being done to preserve the remaining greater bilby population.
