In 2014, standard taxi licences in the city were selling, on average, for more than half a million dollars.

Last year, that figure dropped to $113,003, as the dominance of ride-sharing service Uber sounded a near-death knell for Brisbane taxi licence owners.

The value of wheelchair-accessible maxi-taxi licences nosedived 60 per cent in three years to $111,179, on average, in Brisbane in 2017.

Across Queensland, the value of limousine licences dropped 76 per cent to $16,529, on average.

The plunge in the value of taxi licences can be revealed following Fairfax Media analysis of Queensland government open data.

Uber came to Brisbane in 2014, and ride-sharing was legalised in September 2016, shaving thousands of dollars from the sale price.

While 58 standard cab licences were sold in Brisbane in 2014, caution seemingly swept the market in 2015, with only 11 transfers, with 30 transfers in each of the two following years.

Taxi Council of Queensland chief executive Blair Davies said many licences were owned by "mum and dad" investors, whose investment was damaged due to the arrival of ride-sharing, which created an oversupply in transport options.

"Many of whom put their whole life into the taxi industry, and the taxi licence was their superannuation," he said.

Mr Davies said there were very few buyers for taxi licences in the market.

"Until we can get some certainty back into the market ... then it's going to be difficult for the people who hold those licences to get a reasonable price for their asset," he said.

"People who are selling those licences are doing so because their situation is desperate."

Mr Davies called on the government to level the playing field in compulsory third party insurance, as taxi licence holders paid $4461.80, while ride-sharing drivers paid $585.30.

He said $20,000 compensation paid to taxi licence holders, capped at two licences, was "completely inadequate".

"They need to find some more money to help out people who have seen their superannuation assets devastated by this government policy," Mr Davies said.

"The government really now needs to start getting serious about reviewing what it's done and fixing the problems."

Limousine Association Queensland president Frank Bonomo said many people had lost their retirement nest egg.

"Their income is reduced and their asset, they can't really sell... Realistically they can't do anything about it," he said.

"We've got people who have lost in excess of $1.2 million for 10 licences all because of a stroke of a pen to allow ride-share."

Mr Bonomo called for greater compensation for taxi and limousine licence-holders.

LNP transport spokesman Steve Minnikin said Labor's compensation package of $20,000 per licence, capped at two licences per owner, was "woefully inadequate".

"Mum and dad taxi owners whose licences were their retirement nest eggs now face a bleak future," he said.

A Transport and Main Roads spokesman said the government had provided support to the taxi and limousine industries through the $100 million Industry Adjustment Assistance Package, which included financial, advisory and incentive measures.

The package included $59.78 million in one-off transition payments made to eligible taxi and limousine licence holders and $26.7 million in industry hardship payments.

The spokesman said the government also funded $5.6 million to incentivise wheelchair-accessible taxis, $3.75 million for business advisory help and $4.3 million in waived fees for the existing industry.

Licence holders also had renewal fees waived for 12 months.

No new taxi licences were to be issued before 2018, and none have been issued so far this year.

"Department of Transport and Main Roads will continue to monitor the demand for taxi service licences," the spokesman said.

"Decisions about the need for additional licences and the number/timing of licences to be released will be based on demand analysis."

Last month, there were 3257 taxi licences and 574 limousine licences.

Uber was contacted for comment.

Licence sales recorded at zero dollars, often the result of transfers between family members or trust structures, were removed from the analysis.
