China seems to be where most things are imported from these days.
My friends husband has all his laminate made in China now and imports it from there. He also imports other stuff, have also noticed lots of flat pack stuff is coming in from China these days.
I would have a google as there are so many people in the kitchen business these days and see what is around. Price is always going to be the attraction.
We just had a new kitchen flat pack dh put it in, ordered it from firm here waited about 3 weeks which was ok for us and its very good. Much cheaper than others.
Kitchen Designs | Kitchen Renovations | Flat Pack Kitchens Melbourne, Geelong don't know whether they are in Perth but there are a few on line ones around these day.
Good luck
