Matt Pfahlert, the representative of the mystery investor group which confirmed its purchase of the property last week, has written to Indigo Shire wanting the advisory body dissolved.

The new owners would prefer to deal directly with the council's executive staff and councillors to advance redevelopment plans.

Mr Pfahlert, who declined to comment on the shock move until next week, wrote to Indigo mayor James Trenery outlining the new owners' reasons for wanting the advisory group sidelined.

"We have solid working relationships with local community members and investors, the Hume Regional Development Australia, Regional Development Victoria and Tourism North East already," Mr Pfahlert wrote.

"We have established contacts within a number of other government agencies like Heritage Victoria.

"We see no reason to engage with the sub committee.

"While we understand the reasons for the sub committee’s establishment, we see the circumstances around ownership of the gaol this time around as being very different."

The advisory committee, chaired by Indigo councillor and former mayor Bernard Gaffney and includes representatives from the town's chamber of commerce, was established when the jail was sold to the the Dunnet Group late last year.

The committee will meet on Monday.

Cr Gaffney said the advisory committee was the only voice the Beechworth community had to protect the jail and surrounds from "unwarranted commercialisation".

"I've got grave concerns as to the motivation for Mr Pfahlert wanting this committee dissolved," he said.

"He may see it as a hindrance to whatever he has planned of which the committee and community are unaware.

"The committee was formed by council and would have to be dissolved by council.

"Not at the whim of an investor."

Cr Trenery said the situation had changed significantly with the new owners being locally based.
