Hello all,
Just thought I would add a bit to this thread, since the emergency continues to gather steam.
I am sure everyone here has seen the chaos in Europe, Iran, the US and now beginning elsewhere too. 
The Great Toilet Paper Shortage is now heading into just about every other item in the shops, now also including medicines... and the supply shock for many things is now starting to really bite.
Quite a few medications are made overseas and imported, and with the run on these, the local chemist has told me that they are not even getting dates for when they will be back in stock, including a number of important heart medications that a number of older people are on. Made overseas. An aspect that will bite the longer this business continues.
A friend of mine out west, over the mountains, told me about convoys of Asians pulling into towns, buying out all the goods in the shops there, and throwing it into trailers before heading off.
Fights and now knives being pulled in the supermarket aisles.
Senior hour at the shops failing because the shelves have not been restocked.
Cash drying up, hundreds if not thousands of businesses hocked up to their eyeballs, big and small, with debts greater than those before 2008.
Mass layoffs of staff. Qantas alone shedding 20k. Use up your leave then leave without pay.
Tasmania throwing up the walls and the keep out sign.
International travel basically dead in the water.
It didn't take long for this thing to go into overdrive. What will be next?
