Australia's Black Economy Taskforce has come up with a list of 35 "consumer-focused" proposals to crack down on cash. The taskforce blames consumers for holding cash and for not getting receipts.

Michael Andrew, the head of the taskforce, proposes nanochips in $50 and $100 notes so the government knows where the cash is. Cash will expire after a designated period of time.

Andrew believes "consumers are part of the problem". He wants to punish people who pay in cash and don't get a receipt.

A plan to strip consumers of their legal protections if they pay in cash and fail to get a receipt has been slammed as "completely unfair" by leading advocacy groups.
