By bus
Coach Services comprehensively cover the towns in the South West of the state. Greyhound run a coastal service from Perth through to Broome and onto Darwin via Kununurra.
By plane
Given the distances involved, plane travel is a vital connection to many Western Australian communities. Many towns based on mining have private 'Fly-in Fly-out' FIFO services for their employees, which are difficult for travellers to access.
Most larger towns have some form of commercial scheduled air service. Charter services are commonly available to access more remote areas, and airstrips available for landing are available even in the very smallest towns. If you can get a group of 6 together, a charter flight need not cost significantly more than a scheduled commercial service, but don't expect to be able to each take your 23kg suitcase on board.
By train
Train services are limited outside of Perth and Mandurah. In addition to the Great Southern Railway's Indian Pacific, there are three regional train services all operating from Perth.
The Australind, runs down to Bunbury. every morning and evening.
The Prospector runs out to Kalgoorlie, every day, with coach connections onto Esperance
The Avonlink runs up to the Wheatbelt at Merredin
By car
If you want to travel across WA by road, be ready to drive a lot to get from point A to point B. There are only a limited number of sealed roads any map of the state will probably show you all of them, if you plan to leave them to get to more remote areas you will need to consider renting a 4WD. Contact the company to which you rent the vehicle to check the policy concerning driving on unsealed tracks, as you might have to get their authorization. Driving a rented conventional non-4WD vehicle on an unsealed track may breach your rental contract and void your insurance. Check with the local depot before arriving.
