WIN TV has axed its regional news broadcast in the SE and Riverland, effective immediately.
Staff were informed of the decision yesterday morning and their positions made redundant.
It is understood 10 editorial jobs have been cut because of significant pressure to reduce costs at the station.
Liberal candidate for Barker Tony Pasin expressed his regret and disappointment upon hearing the announcement.
"I was shocked to hear about the decision and feel disappointed for the communities and families in Barker, who will lose access to free, nightly television news broadcasts and updates from their local regions."
He said the loss of this regional media service was "another blow” to country south Australians and is indicative of the continued marginalisation of rural and regional issues.
"Today, more than ever, it is vital that rural and regional residents and communities have access to information and news that is relevant to them and their local regions in order to stay fully informed and up to date on current issues and events.
"The loss of the WIN news service will certainly be felt in the Riverland and SE."
Given his concerns, Mr Pasin has sought an urgent meeting with the management of WIN News in order to express these concerns directly to WIN TV and to attempt to persuade them to reinstate the service.
He also expressed his sympathy for those who had lost jobs or been asked to relocate.
"To see jobs pulled out of rural and regional areas and services centralised in capital cities is a great concern and one of the biggest challenges facing communities throughout Barker.
"If We are to attract and retain young people and new residents in our regions, we need a rich fabric of industries and long term, competitive and sustainable opportunities on offer."
WIN TV has been contacted for comment but is yet to respond.
