With unprecedented times ahead because of the rapidly-changing coronavirus situation, businesses have been faced with a tough reality including closures.
Owner of the Portside Tavern Brad Perks said despite losing his entire life's work, he is concerned about the staff he has had to let go and the flow-on effect this will have on their families.
"This is 30 years of our life's work, built from nothing, that has just closed down," he said. "We are all going to be unemployed, all 24 team members plus us as owners and directors with no income ... it is just horrendous.
"A lot of our team are the bread-winners of their families so it is not us directly - it is the families who are affected and that is what I am really worried about."
Mr Perks said he had considered staying open and offering takeaway services, but when it came down to numbers in the next six months, it was just not going to work.
"It is something that we have looked at. but the cost to still operate and keep the venue open far outweighs the revenue we believe we will receive," he said.
Despite business being tough in the past five years, Mr Perks said this kind of a loss was going to have a flow-on effect. "It is not just about my team who I am really worried about, but my concerns also lay with how this will effect everyone," he said.
"All of our suppliers we will not be able to pay. If you multiply that by every other venue which has closed, that is a lot of people without a job."
The owner of other small businesses in the Yorke Peninsula, Mr Perks said it breaks his heart that it has come to this.
"I worry about the families of our team members. They are like family to us and I am really hurting for them," he said.
Mr Perks said he will continue to offer support to his team members by providing them with advice and directions on how to stay safe during this time and filling out job-seeker applications.
"I want everyone of our team members to be getting a pay cheque next week," he said.
"We will be filling out a form ourselves, whether we qualify I just do not know.
"The world is going to change in six months When we come out the other side life will be very different."
New restrictions were put in place as of midday on Monday to restrict businesses from opening for the foreseeable future.
