There is no requirements now that business names have to be match closely the domain name.
That changed a few years back about the same time the one domain per business name/ etc / no selling rules where in place.
What happened then was a lot of major corprate companies started buying generic domain names also in addition to using their own brand and company named websites
When AUDa decided to auction off generic names it previously had all reserved many of Australia's biggest corporates bought up heaps of generic words with no direct link to their brand name or company name. Now some of those name have been sold around / expired etc and so now its pretty open market.
