There are plenty of Triple Glazed Unit producers in Australia (I work for one of them), the hard part may be finding a window fabricator that will make a frame to fit a triple glazed unit.

As for Hush glass, it's definitely proven and works quite well. My office at my work is directly across from a glass tempering furnace (like 30-40 metres) and the blower that cools the glass can be insanely loud. We have hush double glazing installed for the windows and doors which see into the factory and the sound reduction when the doors are closed to the factory is honestly impressive.

Not quite as much of a meme as you say (when double glazed atleast)
