• The redistribution has abolished the Liberal seat of Eyre that previously ran from Esperance to Boulder. In its place Kalgoorlie now takes in both Boulder and Kalgoorlie while Esperance is included in the new seat of Roe, which also takes in large parts of the abolished seat of Wagin. Both Roe and Kalgoorlie remain as notional National Party seats.
• The south-west seat of Collie-Preston has been re-drawn to take in Donnybrook-Balingup Shire, turning this previously marginal Labor seat into a notional Liberal seat.
• The re-arrangement of the boundaries of Labor-held West Swan has wiped out Labor's margin of 1.9% and turned it into a notional Liberal seat.
• The Commission initially proposed to use non-geographic names for a number of seats when draft boundaries were released, but has reverted to geographic names at the final stage.
• A new notionally Labor seat called Baldivis has been created in southern Perth from parts of Kwinana and Warnbro.
• The Liberal seats of Alfred Cove and Bateman have had their previous east-west arrangement re-aligned as north south seats. The Liberal margin for Bateman increases from 17.8% to 23.1%, but the new seat of Bicton has a margin of only 10.0% compared to 23.6% for the abolished seat of Alfred Cove.
• Other seats to adopt new names include Thornlie (formerly Gosnells), Burns Beach (formerly Ocean Reef) and Roe replacing the former seats of Wagin and Eyre.
• There has been a general counter-clockwise rotation of seats around northern parts of the metropolitan area. Butler in the far north has been diced and spliced, West Swan moves west, while Swan Hills slips out of the hills and becomes an Ellenbrook based seat.
• Other seats to see substantial changes in margin include Burns Beach (formerly Ocean Reef Liberal down from 19.0% to 11.3%), Fremantle (Labor margin up from 7.9% to 15.4%), Jandakot (Liberal up from 8.1% to 18.3%), Joondalup (Liberal up from 4.5% to 10.1%), Kwinana (Labor down from 11.8% to 4.3%), Southern River (Liberal down from 17.0% to 10.9%) and Willagee (Labor down from 10.6% to 2.5%).
