Money has made a slight come back here, but generally higher end shops and big purchases like say a car or major home appliance they will not take cash money, but cash as in like a debit card with no chip (So processing fees are minimal or non existent.
Many retailers encourage credit card, as you can charge surcharges inposed by all our greedy Australian owned banks, but many shops will charge extra as a kick back.
Capitalism is king here now and many stores will push extra warranties and hire purchase for big ticket items. They hate cash buyers like me, because their profit margins are cut. Capitalism is based on greedy, stupid and poor people not the well off, astute or sensible like myself.
Smaller shops, dairies, food outlets etc, accept paper money - less keen on coins unless a tiny purchase. I am amazed when they whip out the eftpos terminal for even trivial purchases under $5 (Virtually nothing costs cents only unless a tiny lolly or single pencil). They always look dejected when they see that old fashioned papery stuff and those round metal things the 17 year old sheltered employee heard about from her grandparents, that we used in the days we hunted dinosaurs for dinner and there was no Snapchat or Facebook.
But its a recommended law here than coins of 10c, 20c and 50c are only legal tender up to and including $5 and those of $1 and $2 to $20.
