What makes you think Minor Mania producer of the parts catalogue above is Australian especially as it has a North London telephone number?
Minor Mania were (and what remains of Minor Mania is still possibly) based in Mill Hill North London.

Minor Mania started producing Morris Minor modifications way back at about the same time as Grumpy's started making Minor modifications.
The most helpful of Minor Mania modifications IMO was the production of negative camber eye bolts with negative camber adjustment spacers of 2, 3 and 4 degrees. I have a pair with spacers - see photo below.

They also produced eye bolt, top trunnion, spring eye bushes and clutch relay shaft bushes in plastic way before the advent of poly bushes. I have NOS examples of all those bushes.
They had a twin rear axle pickup and modified Minor as advertising tools.
They used to have full page adverts in Minor Matters for some considerable time.
You are right in that there is a company in Australia with a similar name - Minor Mania (founded 1995) but as far as I know has no connection with the UK company.
but when submitted appeared upside-down.
