Glenorchy ratepayers paid $369,000 to former general manager Peter Brooks in the last financial year despite his employment ending in November.

Documents obtained by the ABC under right to information laws revealed one Glenorchy Council employee received a total package of $369,742 in the last financial year.

It is understood that employee, the council's highest paid, was Mr Brooks, who was on leave from the council until November when his employment ended.

Included in the total package was a payment of $192,841, which is understood to have been a termination payment.

The revelations came as Glenorchy residents face a 12.5 per cent rate rise this year following years of dysfunction and infighting at the council.

Phil Butler, from the Glenorchy Ratepayers Group, said given the circumstances around the council's dysfunction, the payment was a "disgrace".

"The money paid out to Brooks and his deputy quite frankly is a disgrace, an absolute disgrace," he said.

"When you add it to the added cost of paying other staff to do their work while they stayed at home twiddling their thumbs, it must be close to a million dollars."

In May, a damning Integrity Commission report tabled in Parliament made findings against Mr Brooks, the former director of corporate governance Seva Iskandarli and former mayor Stuart Slade over attempts to improperly gain financial benefits of up to $1 million.

'Brooks sought to increase termination payout'

The Integrity Commission found Mr Brooks and his lawyer suggested a number of changes to his own contract in 2016 — including one that would have provided him with a payout of 12 months' salary or the remainder of his contract (up to five years), whichever was greater, if he was terminated for poor performance.

Mr Brooks's contract was due to expire in 2020.

The council was recommended to approve the proposed changes, but a special meeting called to consider the new contract was adjourned by Mayor Kristie Johnston before it could be voted on.

The Integrity Commission found "Mr Brooks sought to increase his termination entitlements due to his concern that his employment would be terminated as a result of the board of inquiry process".

Ms Johnston said the remuneration information would be presented to the council at the October 29 meeting, but the council had decided to release it under right to information in the interests of transparency.

"Arrangements previously entered into by the Commissioner and any former senior employees cannot legally be discussed," she said.

"However, council has a duty to disclose all payments to key management personnel as part of its end-of-year audited financial report.

"We take compliance with this duty very seriously."

Ms Johnston said new general manager Tony McMullen received a total package of $265,513 in the 2017-18 financial year.

Mr Brooks declined to comment.
