Royal Adelaide Show organisers will consider a cashless future, after more than $30,000 was stolen from the South Australian Country Women's Association stall.
Last Tuesday, a man confronted CWA Deputy President Sharryn Muller and demanded the cash while she was looking after the stall.
Ms Muller was forced to place a large amount of money in his backpack.
She collapsed after the ordeal.
Incoming Royal Agricultural & Horticultural Society of SA CEO William Rayner told ABC Radio Adelaide a review was now underway.
He said it had also been revealed that the Bank SA ATM the charity normally uses was not available this year.
"It's left a bad taste from a fantastic event," Mr Rayner said.
"The money's been covered through insurance thankfully.
"We have extensive police presence both uniform and non-uniform – we have our own show security.
"We've been working for CWA for decades ... it's clearly something we need to look at."
Bank SA said in a statement that it was sorry to hear of the situation but had closed the showground branch because the majority of consumers and vendors preferred to use digital payment methods over cash.
Cashless future?
Adelaide Royal Show organisers have been in discussions about a cashless future, following other events including the Sydney Royal Easter Show.
Will Rayner said the lack of cash in use was prevalent at this Adelaide's event.
"Just 6 per cent of tickets bought at the gate were using cash," Mr Rayner said.
"The use of cash is declining rapidly.
"There are protocols in place, and we will be looking very closely at this one.
"We just need to make sure those who do use cash are protected."
Authorities seek information
Earlier this week, police released a computer-generated image of the man who robbed the CWA.
He was described as Caucasian, aged in 40s, about 165-centimetres tall with grey and black facial hair.
Police said the man had a "distinctive" horizontal scar above his left eyebrow and tattoos on his left forearm.
He was wearing black jeans, a black top with Led Zeppelin on the front and a green cap — a comfit of the man shows him in a black cap.
Anyone with information is urged to contact Crime Stoppers.
