In the 1990's, what home appliances were available in developed nations, particularly Australia?
When it comes to things like appliances, the 1990s were essentially no different than our lives today. There are a few kinds of appliances that have changed in important ways, but there are no major appliances that we have now that we did not have then.
The main things that we have now that were not around in those days are electronics. There were no digital cameras in those days. There were very few cell phones and, of course, no smart phones. There were no iPods or e-readers. But those are not typically seen as appliances.
When it comes to appliances, the ones that have changed the most are also electronic. Those are things like TVs and computers. There were no flat screen TVs and computers were not as advanced as they are now. But other things were just about the same as they are now. There were stoves and ovens and microwaves. There were refrigerators and freezers and air conditioners. There were toasters and bread makers and dishwashers. There were washing machines and dryers.
As far as major household appliances, then, things in the 1990s were essentially the same as they are now.
