There was a time that Dick Smith published a catalog like this. It was mostly supermarket products, and needed constant updating as companies outsourced overseas.

Just for my car, I can think of: Motor oil - Penrite instead of Valvoline. Detailing - Bowden’s Own instead of Meguiar’s. Tyres - I don’t think anything is made here anymore. Not even the Bob Jane or Dunlops.

I play baseball. It’s easy to avoid US products, as Japan and Canada make heaps of great stuff. You won’t find anything Australian though.

Most of Australia’s consumer money spent on US products goes to Facebook Amazon Netflix Google and Microsoft.

For tech, I guess Stan instead of Netflix?

I avoid most physical US products because they’re often not metric, and a pain to work with.

For example, the lawnmowers at Bunnings have Briggs ans Stratton or Honda (US) engines. I bought a Rover from an independent mower shop. Great aussie mowers.
