Gaudium jingera was first formally described in 1996 by Andrew Lyne and Michael Crisp in the journal Australian Systematic Botany, based on plant material collected by Lyne from Brumby Point on the Nunniong Plateau in the Alpine National Park in 1994.[4] In 2023, Peter Gordon Wilson transferred the species to the genus Gaudium as G. jingera in the journal Taxon. The specific epithet (jingera) is an Aboriginal word meaning "remote and mountainous, bush-covered country", referring to the habitat of this species.
Stringybark tea-tree grows in low woodland and shrubland and is only known from the type location and The Watchtower in the Snowy Range in Victoria.
This species is listed as "vulnerable" on the Victorian Government Department of Sustainability and Environment's Advisory List of Rare Or Threatened Plants In Victoria.
