Expressions of interest are being sought for a tenant to manage the Mokoan Hub at Winton Wetlands Reserve.

The Department of Energy, Environment and Climate Action (DEECA) took over land management of the reserve on 1 August, after previous committee of management the Odonata Foundation announced in June that it would relinquish management of the 9000-hectare reserve.

DEECA is now seeking a tenant for Mokoan Hub, which comprises café dining and office facilities, through the expression of interest process currently underway.

DEECA Hume regional director Clare Kiely said with great views across the wetlands - which is Australia's largest restoration project - the hub was a unique venue which offered a business opportunity for prospective tenants.

"Proposals that include partnerships, joint ventures or new business ideas that support the existing café offering are highly encouraged," Ms Kiely said.

The hub includes café dining and function facilities, with a modern commercial kitchen.

An additional large room can host up to 80 people, and can be divided from the café.

The outdoor dining area can seat up to 60 people, and overlooks a natural playground featuring a 40-metre flying fox.

An open plan office at the rear of the building which includes two offices is also part of the lease, as well as a board-style meeting room.

"This is a great opportunity for a business-minded individual or group to help influence the future of the wetlands," Ms Kiely said.

The Mokoan Hub was officially opened on 16 May, 2015, won the national sustainable building award in 2016, and has been a focal point for visitors to the wetlands.

Expressions of interest in tenancy of the hub close at 2pm on Thursday, 11 September.
