The interiors of the 1972–73 extensions reflect fashions of the time, although wooden panelling was used for the walls, in keeping with the older parts of the building, but with an unequivocally 1970s style. On the Representatives side, the extensions necessitated the demolition of the Prime Minister's suite of offices (originally intended for the Speaker) and the original Cabinet Room. The rooms are now left in the condition they were in at the time they were occupied by Bob Hawke, immediately prior to the move to New Parliament House in May 1988. Similar extensions were made on the Senate side, with a new suite of rooms being constructed for the President of the Senate in a similar style.
