Business owners on Foreshore Drive have voiced their anger over what they perceive as "special treatment" of Government vehicles by City of Greater Geraldton rangers.

The anger follows a heavy period of fines for cars parked outside businesses on the street near the museum while several Government cars were parked on the sidewalk or on grassed areas.

City spokeswoman Sue Chiera said no Australian Government or WA Government vehicle was exempt unless there was genuine reasons for their presence, such as emergency services vehicles or vehicles utilised by agencies to install-repair infrastructure within or close to the road reserve.

She said an example might be Water Corporation, Western Power or Department of Transport but noted they do need to park safely to undertake that work.

"The marina area does have areas that fall under the responsibility of the City but there are also areas that fall under the responsibility of other agencies such as the Department of Transport, the boat parking area, boardwalk area and surrounds being examples of the latter," Ms Chiera said.
