Tasmanian voters are being bombarded with political advertising in the dying days of the state election campaign, with the Liberal Party and its supporters far outspending their rivals.

Pro-Liberal political advertising has dominated the airwaves, screens and newspapers of Tasmanians.

Advertising has also popped up on children's iPad games, as the Liberals flood social media, Google searches and YouTube.

Labor's policy to remove poker machines from pubs and clubs has angered the gaming industry, and it has opened its wallets to help the Liberals get re-elected.

University of Tasmania marketing lecturer Dr Louise Grimmer said the standout of the campaign for her was the "the absolute scale, scope, reach and spend by the Liberal Party".

"It completely dwarves the amount of campaign materials that have come out from Labor and the other minor parties," Dr Grimmer said.

Based on advertising pricing obtained by the ABC, the pro-Liberals camp far outspent Labor and its supporters.

An estimated $42,596 was spent in The Mercury newspaper over one day on pro-Liberal advertising from the Liberal Party, Federal Group and Love Your Local campaign.

By comparison, an estimated $15,213 was spent on Labor and anti-pokies ads.

On commercial television on Wednesday between 8:30pm and 9:30pm, there were typically four pro-Liberals TV ads to every one pro-Labor ad.

Ms Grimmer said on a recent drive from South Launceston to Bridgewater she counted 167 Liberal billboards, 56 Labor and one Greens.

"The sheer scale of the spread of the Liberal campaign is really significant," she said.

"It is a very sophisticated campaign that the Liberal Party are running. To run a campaign of this scope and scale costs a lot of money."

Liberals spending 'obscene amount of money'

Labor leader Rebecca White estimated the Liberals have spent about $5 million on political advertising, outspending her party 5-1.

"It's an obscene amount of money to be spending in political advertising," she said.

Premier Will Hodgman would not be drawn on the exact figure.

"Rebecca White made that claim. It is a matter for her to substantiate it," he said.

"I am not absorbing myself in the detail of the campaign."

Greens leader Cassy O'Connor said the Liberals had been bought by the gaming industry.

"If the Liberals win majority government on Saturday it will be one of the most undeserved wins and corrupted wins in Australia's political history," she said.

"If they win government it'll be off the back of pokies money — millions of dollars off the back of human misery."
