New South Wales has the largest number and second highest density of motorways in Australia (behind Victoria), with the majority being located in Sydney City or the metropolitan areas.
Memorial Drive (Wollongong) – Most of this road is freeway grade[4] – (The south 4 km of the road and the north 3 km of the road are, the central bit isn't though)
Princes Highway, 16% of which is of motorway or dual carriageway standard.
Barton Highway – 21% of which is of motorway or dual carriageway standard, with the remainder under construction and proposed for completion by the end of 2023. See freeway route here [3]
WestConnex Stage 3 (Major multibillion-dollar tollway/tunnels, connecting the M4 East to A4 Western Distributor and M5 East) – To be completed by 2023.
Sydney Gateway (Connecting Sydney Airport to the St Peters Interchange and WestConnex) [4]
Barton Highway duplication project (To be completed by mid 2023)
While the Northern Territory doesn't have any official freeways, parts of the Stuart Highway and the Tiger Brennan Drive are freeway grade roads with grade separate intersections.
In South Australia, expressway may refer to a controlled access highway with no at-grade intersections or a limited access road of slightly lower standard with at-grade intersections at some locations.
Unlike some other states, South Australia only uses the 'M' designation on grade separated freeways
While Tasmania's highway network has been constructed to a high standard, its grade-separated freeway network is limited. In the past, Hobart and Launceston have each had comprehensive transport studies conducted, proposing grade-separated freeways running through and around them. While some of these roads have been constructed, the majority are limited access featuring at-grade intersections. Devonport and Burnie are the only major population centres with freeway standard roads linking each other. There have been repeated proposals in recent years to fully upgrade the Midland Highway to grade-separated freeway standard.[7][8] This List is limited to Tasmania's freeway-standard roads.
Victoria has the second largest number (behind New South Wales) and highest density of freeways in Australia, with the majority being located in Melbourne City or the metropolitan areas. While most of Australia has a low population density over a large area, where towns are sparse or located a significant distance from each other; Victoria has towns located throughout the entire state, with large numbers of inhabitants, in both urban and rural areas (many of which are major) such as Ballarat or Bendigo. In addition to the roads listed below, Victoria has a number of dual carriageway standard Highways that are given an "M" designation. Whilst these roads are not officially Freeway standard, many of them may have a number of grade-separated intersections along the route. These routes are not listed below.
Melbourne region (urban freeways)
Freeways within Greater Melbourne,[9] speed limit varies between 60 km/h and 100 km/h.
Hume Freeway (from Thomastown to Wallan, continues past Wallan as Rural Freeway) – Not entirely freeway standard, In Kalkallo there is residential property, business and local road access with 80 km/h speed limit.
These roads are officially designated by the Victorian Government as Freeways and may include some freeway signage, but are generally not considered part of the Melbourne freeway network.
Airport Drive (from Western Ring Road to Sharps Road, officially Freeway grade road)[10]
Princes Freeway (West) (continues at Pakenham towards Melbourne as Urban Freeway) – Not entirely freeway standard, In Yarragon and Trafalgar there is residential property, business and local road access with 60 km/h speed limit.
Western Australia has three named freeways – Kwinana Freeway, Mitchell Freeway, and Graham Farmer Freeway – but in addition has several highways that are in the process of being upgraded to full freeway standard and are considered part of the Perth freeway network. Their designation may remain as a highway though due to state restrictions on heavy vehicles (e.g. road trains) that are prevented by law from travelling on any road classed as a freeway.
Forrest Highway – Southern extension of Kwinana Freeway at Mandurah through to Bunbury
Bussell Highway – Bunbury to Capel and from the south side of Capel to Busselton
Under construction
Perth
Mitchell Freeway southbound widening – A third southbound lane is being added from Hodges Drive to Hepburn Avenue as well as an extra lane will be built from Hepburn Avenue entry ramp to Warwick Road exit ramp.
Tonkin Gap project – the currently heavily congested section of Tonkin Highway between Collier Road and Great Eastern Highway upgraded to 3 lanes each way dual carriageway
Rural
Bunbury Outer Ring Road extension – the Bunbury Outer Ring Road will be a freeway between Forrest Highway and South Western Highway[16]
Albany Ring Road – phase 1, with phase 2 to commence straight after completion of phase 1
In planning
Perth
Mitchell Freeway Extension (Romeo Road to Moore River)[14]
Mitchell Freeway southbound – Installation of smart freeway technology with ramp metering from Hester Avenue to Vincent Street
Roe Highway Extension (Perth Freight Link) (Kwinana Freeway to Stirling Highway). Was under construction but this was halted at the last change of government. Its future remains unclear.
Roe Highway upgrade (Great Eastern Highway Bypass to Great Northern Highway)
Reid Highway upgrade (Erindale Road to Mitchell Freeway, Altone Road to Great Northern Highway)
Tonkin Highway upgrade (Hale Road to Mills Road)
Tonkin Highway upgrade (Champion Drive to Thomas Road)
Orrong Road Upgrade – Orrong Road to be upgraded to a 4 lane trenched expressway with service roads alongside from Graham Farmer Freeway to Leach Highway, rising onto a viaduct over Leach Highway and Division Street/Bell Street. May be extended in the future along Orrong and Welshpool Roads as far as Tonkin Highway.
Great Eastern Highway Bypass, where all current at grade intersections are planned to be removed and the road upgraded to full freeway standard.
Rural
Busselton Outer Bypass (BOB)
Perth–Adelaide Freeway "Orange Route" – (Roe Highway, Stratton to Great Eastern Highway bypass at Northam)
