That engine was built in Briggs' Poplar Bluff, Missouri, engine plant. They have not now and never have had an engine plant in Brisbane. The only overseas engine manufacturing plants they have ever had making side valve engines were in China and in the Czech Republic. The Czech plant was closed a few years ago. The China plant is now the only Briggs plant making side valve engines. The relatively few surviving US plants now only make OHV engines.
Briggs has however had numerous depots around the world where imported engines are unpacked, prepared for sale, and despatched to dealers.
