Labor will demand answers in the NSW parliament regarding why Campbelltown Arts Centre missed out on an Australian Council of the Arts grant while many other projects in Liberal and National Party held seats deemed unworthy were successful.
Former NSW Arts Minister Don Harwin and Nationals leader John Barilaro approved more than $3 million in grants in coalition-held seats for 13 regional arts projects judged ineligible by an expert panel.
Campbelltown Arts Centre recently was rejected for funding which angered many in the community.
Campbelltown MP Greg Warren will submit a Notice of Motion in Parliament demanding answers regarding the grants and why Campbelltown Arts Centre missed out.
"It is vital that there is complete transparency regarding the awarding of state government grants - who they go to and why, and importantly, who they don't go to and why," he said.
"It seems to be a common theme under the Berejiklian Government where funding favours those in Liberal and National-held seats.
"There is no point in consulting experts if their opinions and views are continually dismissed."
Deputy Premier John Barilaro denied any wrongdoing to the ABC and laughed off pork-barreling claims.
Mr Barilaro said the Regional Cultural Fund's purpose was to "deliver real benefits to real people, not satisfy only arty types who sometimes populate these departmental panels."
