I suppose I should elaborate.
Onyx was the Australian branding of a company that did copies of instruments in the '80's
I cannot find pictures of their Tele, But here are a few others...

They were a fairly reliable Japanese made brand and the Tele was my only stage and recording guitar for many years.
It was stolen twice, and reclaimed both times. One time the perp even sanded back and scratched away at the headstock, removing the logo.
The guitarist from a band we used to share billing with dropped a Di'Marzio bridge pickup in her, and she knows how to scream and be sensible.
She was made I must assume during the timber shortage in the 80's when factories turned to different woods. She appears to be a form of ply (layers in cross section) but has a great sound and sustain.
I recently treated her to a facelift. Respraying the black body to now be a Charcoal metallic and matching the headstock, fitting all black hardware and applying an ebony stain to the rosewood fretboard. As a further point of difference, I fitted a pearlescent blue pickguard.
Bought it for $60. $50 worth of refit/ respray.
Love this guitar.
