The number of Uber drivers in Perth is now half that of taxi drivers as the ride-sharing service continues to rapidly expand its share in the transport industry less than two years since it launched.

Since Uber kicked off in Perth in July 2014, the number of taxi drivers registered in Perth has dropped nine per cent from 6948 in 2014 to 6375 in 2016.

Uber is catching up to Perth's ailing taxi industry.

Taxi Industry Forum WA chairperson Howard Lance said he blamed the industry's poor attitude towards customer service and its outdated booking and dispatch technology.

Meanwhile, Uber has experienced a surge in the number of drivers registered - from 1500 drivers in mid-2015 to 3200 drivers in 2016.
