Xero (also styled as Zero or Xiro) were an Australian punk rock and new wave band formed in 1978 in Brisbane, Queensland.
They were fronted by mainstay member, Irena Luckus on lead vocals, keyboards and guitar before disbanding in 1983.
By 1978, now including Vic Allen, Deborah Thomas and Lindy Morrison, the band travelled across New South Wales by train, playing gigs in Canberra (in a large, very cold hall) and Newcastle (in a local pub).
Xiro issued two different four-track extended plays, Half the Profits and Religious Wars, on audio cassette in mid-1980.
Luckus and Willsteed were then joined by Clare McKenna on drums to become Xero and entered a period of intense song-writing in their Fortitude Valley practice rooms, and performing at various Brisbane venues.
