Dorchester Hall. Dorchester Hall is a City of Joondalup-managed community hall at 2 Dugdale Street in Warwick, Western Australia. The council's community venue accommodation table lists 50 people for its Main Hall, not the 300-person capacity of the separate Warwick Hall. The space hosts local club and group activities and is available through Joondalup's venue booking system. Table arrangements can lower actual occupancy; equipment and kitchenette facilities need separate confirmation. Confirm current booking availability, permitted uses, current prices and the precise inclusions directly with the operator.
