I thought this article was interesting

Home brand auto parts to rev up beyond Coles, Woolies supermarket levels

Some key points:

Bursons now own Autobarn, Autopro, ABS and Midas and is a locally listed ASX company

Repco is owned by a US parent company (I didnt know that)

Supercheap is a locally listed ASX company

Repco seems to have lost its way a bit at the moment. Supercheap is killing them from a marketing perspective, and Bursons is leading everyone on trade supply to workshops. Will be interesting to see what they do.
