In addition to a management model beyond June 30, the council is also grappling with the full extent of improvements needed to bring the park up to standard.

Other items kept secret from ratepayers in a marathon confidential session included a lease deal at Corowa airport, the rejection of the outcomes of a report into construction and design of Corowa playground Bangerang Park and a Mulwala land sale which was a late agenda addition.

General manager Adrian Butler said the long list of confidential items was allowed under the Local Government Act with council being ultra cautious since the introduction of live streaming of meetings.

"We've just got to play a pretty straight bat," he said.

Councillors unanimously voted for all items to be dealt with behind closed doors on Tuesday.

Ten items were dealt with in a confidential session last month.

In his report to open council, Mr Butler made reference to major issues at the council-owned caravan park.

"Council are aware that the park is undergoing the very early stages of a much needed and required extensive renewal phase for safety, risk and amenity purposes," he said.

"Council are also aware that the park presents many challenges in this process, in terms of the age of its infrastructure, the layout of sites and structures, and many serious compliance, safety and risk issues including the many red-gum trees within the park in the direct proximity of sites."

Council previously identified $285,000 worth of improvements required at the park in the short-term.

The 12-month contract in place with BelgraviaPro to manage the caravan park expires on June 30.

BelgraviaPro took over the park management from long-time operators, Andrew and Sonia Palmer last year.

But the move has been dogged by controversy with the revelation BelgraviaPro had submitted a non-conforming tender.

Council will not re-tender the park management post June 30 and will run the facility itself.

Also, any park occupancy agreements, which includes some long-term patrons, won't be renewed after the same date.

"Due to the age of the park, council has been required to have various reports completed including with regards to risk of trees, and other fire safety and compliance matters," Mr Butler said.

"Council will operate the park under an employee model as a visitor accommodation venue including 20 cabins and powered sites post June 30.

"Council values the significant contribution that all users of Ball Park caravan park have made to the area over many years."

COROWA AIRPORT COUP

FEDERATION Council has entered into a lease deal with Amber Aviation Academy to establish an aviation training facility at Corowa airport.

Amber Aviation Academy educates and trains commercial and general aviation pilots and proposes to also facilitate cabin crew, ground support crew, aviation engineers and technicians from the Corowa facility.

Its long-term goal is to create more than 150 jobs.

"Council is thrilled to be announcing our successful partnership with Amber Aviation Group, who we will work together with to achieve a long term economically sustainable future for the Corowa airport supported by this expansion," Federation mayor Pat Bourke said.

"Council will now pursue opportunities for grant funding to upgrade current facilities for the betterment of all stakeholders."

The deal was confirmed in the confidential session of council with no details including lease length or terms released to ratepayers.

Amber Aviation group chief executive Mahendra Naidu said: "Our planned expansion will eventually create over 150 new jobs, comprising of flight instructors, trainers and assessors, engineers, managerial staff, administrative staff and support staff."
