The State Hall looking east to the entrance to the State Dining Room. This is one of the great interior spaces of Government House. Its 32 metre length is balanced by its high cross-vaulted ceiling. The overall style of the house, announced by the State Hall, is a restrained classicism, able to adapt itself to changing functions and tastes.

The room is framed by engaged and freestanding Corinthian columns and pilasters. In the past, settees in the centre and potplants on the sides made the room appear more crowded, and less of an arcade or transit area than today.

The highly variegated colour scheme of former times has been reduced to plainer lines and hues. Natural light from the clerestory windows is complemented by the muted colour scheme.

A feature of Government House is its collection of original Australian furniture and joinery made by two Melbourne firms, James McEwan and Company and George Thwaites and Son. The oval supper tables of inlaid walnut, and inlaid fiddleback blackwood, and the upholstered settees along the walls, are examples. There are polished cedar architraves around each door.

On the left wall is a portrait of the reigning monarch, Her Majesty Queen Elizabeth II, commissioned by the State of Victoria for the Sesquicentenary in 1984 and painted by Brian Dunlop. Bronze incense burners are placed at the foot of the columns in the foreground. The State Hall is used for small formal occasions, as well as receptions after ceremonies in other State rooms.
