Source of thick wall RHS cut to size in Melbourne

I'm trying to build my own small foot print mill. I like the idea of using thick wall (9-12mm) RHS (rectangular hollow section), but I can only find sources in Melbourne that sell full lengths (8m). Does anyone know of a source that sells short lengths (1 or 2m). It appears this isn't a common size, so nobody wants to keep part lengths in stock.



My design is currently using 200x100 and 100x100 sections. If I'm force to buy and 8m length, then I'll have to redesign to use 50x50 (or thereabouts) and stack them up (weld or bolt together).



Thanks,

Frank
