A new passenger charter service that operates through smartphone technology will be officially launched in Perth today despite ongoing discussion within the WA Government about how to regulate it.

Uber, a San Francisco-based company, already operates in several Australian cities, including Sydney, Melbourne and Brisbane, as well as 100 cities in 35 countries around the world.

The service allows commuters to use a smartphone app to book private charter vehicles after providing personal information, including credit card details.

No cash is exchanged - instead, fares are automatically charged to a passenger's credit card after a journey.

At its annual state conference next month, the WA Liberal Party was expected to debate a motion calling on the State Government to remove legislative and regulatory barriers preventing consumers from using such services.

One of the main barriers is a minimum $60 fee for passengers to use the service in Perth.

The fee applies to all charter service vehicles in WA and exists under regulations put in place to protect the taxi industry, but the issue for Uber is that many fares cost less than $60.

The ABC understands that some Uber drivers are openly flouting the regulations and accepting fares less than $60.

Meanwhile, some in the Liberal Party believe Uber drivers need to be trained and regulated under the same system as the existing taxi industry.

Transport Minister Dean Nalder, who is on leave, previously said the safety of passengers and drivers was the Government's first priority.

"This is why initiatives such as cameras in taxis, and the compulsory reporting of criminal offences committed by taxi drivers to the Department of Transport, have been put in place," he said.

But others in the Liberal Party say that in other countries, moves by governments to try to control new types of passengers services have failed.

They say consumers should be able to decide for themselves which service they want to use without government interference.

The existing taxi industry is heavily regulated and some Liberals believe the new service will threaten its viability.

Policy motions passed by state conference are not binding on the parliamentary Liberal Party.

The soft launch of the service in Perth in May caught the Transport Minister by surprise, leading Mr Nalder to say he would ask his department to investigate whether the company was complying with the law.
