Ms Ryan was involved in awarding more than $10m of public money to a company on the verge of bankruptcy The Gunner Government has refused to investigate why the funding was approved

The Gunner Government was also accused of "collusion and corruption" in Parliament by an independent MLA for refusing to investigate how the now-insolvent NT Beverages was able to secure the public funds while heavily in debt to the NT Government.

Marion Scrymgour, a former Labor deputy chief minister, called for Ms Ryan to resign over her involvement in the matter.

"Jodie Ryan should step down," Ms Scrymgour said in a Facebook post.

"Maybe this is one for the ICAC Commissioner?"

Former Labor leader and treasurer Delia Lawrie questioned the current Labor Government's accountability to Territorians.

"This is outrageous," Ms Lawrie posted on Facebook.

"Accountability anyone in NT Govt?"

Independent MLA Robyn Lambley told Parliament on Tuesday that the now-defunct Northern Territory Infrastructure Development Fund's (IDF) investment in NT Beverages, which recently went into voluntary administration, should be investigated.

"Who gets given $10.5 million of taxpayer money with no strings attached and no explanations required?" she said.

"No responsibility, no explanation.

"The Government has no appetite to look into this matter.

"I do not know about anyone else, but to me, that sounds like collusion, perhaps corruption. It sounds like it could be misconduct …"

Almost $10m blown in four months

The ABC reported on Monday that an administrators' report to creditors of NT Beverages showed the company owed more than $220,000 to the NT Government in unpaid stamp duty in February 2018, but was given $10 million of public funds that same month.

The company went into voluntary administration in December, but the report questioned whether it may have become insolvent before that.

The report into NT Beverages also showed that the company was given a $100,000 taxpayer-funded loan last September, after blowing through the initial investment in just four months.

It also revealed the company did not pay payroll taxes to the NT Government for the 2018 financial year.

The Infrastructure Development Fund was enacted by Treasurer Nicole Manison in late 2016 to operate as a private entity despite being funded with $200 million of taxpayer money.

It only made the one investment in more than two years and was decommissioned late last year.

The NT IDF board consisted of former Infrastructure Capital Group executive director Les Fallick, Paspaley Pearls CEO James Paspaley, former Macquarie Bank boss Bill Moss, former Future Fund managing director Mark Burgess and head NT Government public servant Jodie Ryan.

'Utterly incompetent'

Ms Ryan, who was the NT Government's only board member on the IDF, blamed fund manager Infrastructure Capital Group for the investment decision, but did not answer questions over her role in approving the money.

ICG closed their Darwin office and calls to the company's Sydney headquarters have not been returned.

Ms Lambley's comments were made while Parliament debated a censure motion against the Gunner Government for plunging the Territory into a serious financial crisis.

Ms Lambley said the $200 million IDF and its investment was one of the worst examples of financial mismanagement in the Territory over the last decade.

"This exemplifies how completely and utterly incompetent this Government is," she said.

"At the end of the day you will have to be accountable for all the money that disappears under spurious and suspicious circumstances.

"You can't just let $10.5 million of taxpayers' money just disappear and offer no explanation and offer no option of investigation."

Chief Minister Michael Gunner's office has not responded to questions over why the NT Beverages investment has not been referred for investigation.

On Monday, he said he had confidence in Ms Ryan's abilities.

Ms Ryan's spokesperson said she had no comment.
