A new poll shows Labor MP Kate Jones has clawed back ground from Liberal National Party (LNP) leader Campbell Newman in the crucial Brisbane seat of Ashgrove.

Mr Newman has to win the seat in Brisbane's inner-west if he is to become the next Queensland premier.

Previous surveys have shown he is likely to do that, but the latest ReachTel automated phone poll of 742 residents in the electorate shows Ms Jones is gaining ground.

Ms Jones' primary vote in the seat has increased 3.4 per cent to 44.4 per cent over the past month.

Mr Newman's primary vote in the seat has slipped 3.8 points, but he is still slightly ahead with 45.4 per cent support.

The sample of the 742 residents in this survey has a margin of error of +/- 3.5 per cent.

There has been a steady decline in primary support for Mr Newman since ReachTel started polling the electorate in September.

On a two-party preferred basis, Ms Jones leads Mr Newman 50.7 per cent to 49.3.

Tough battle

Ms Jones says she has always expected a tough battle to retain the Ashgrove seat, but is heartened by the poll.

"There are a lot of electorates where there are tough battles," she said.

"What I think this shows is what I'm feeling on the ground - which is the more the people of Ashgrove see Campbell Newman, the more doubts they have of Campbell Newman.

"There is no doubt that this message clearly shows that the people of Ashgrove want someone who lives among them and is part of their community.

"Campbell Newman doesn't live here and has said even if he wins, he will not live here.

"That really is sending a very clear message that he's only using Ashgrove as a stepping stone to [government in] George Street."

Mr Newman says he is expecting a tough fight until polling day.

"I'm very confident the people of Ashgrove know what's at stake and know that on the day they'll make a decision to back a positive change for Queensland," he said.

"I think there's a lot of work for us to do to get out and sell the message."

However, Mr Newman again would not be drawn on who would be premier if he loses Ashgrove but the LNP wins government.

He says that is hypothetical.

Funding promises

Meanwhile, Mr Newman will still not say how he will fund his election promises, saying again he will release the details before polling day.

The LNP says it has so far committed to around $3.6 billion over the next "four-year budget cycle".

There are also longer-term pledges.

When making policy announcements, Mr Newman has not been outlining how the pledges will be paid for.

Mr Newman says his promises will be funded through savings but will not elaborate yet.

He says detail will be released before polling day, but will not say how long the public will have to scrutinise it.

Mr Newman says Opposition treasury spokesman Tim Nicholls is working through details with former auditor-general Len Scanlan.

"I just say to you we're doing exactly what has been done for many, many decades," Mr Newman said.

"It'll be before the election - just like it always has before."

However, Premier Anna Bligh says the LNP should follow Labor's lead.

"Every promise Labor has made we have put in the release and the policy where the money is coming from," she said.

"Anything [Mr Newman] promises today has to identify a funding source, or people need to know that it just won't happen."

Infrastructure pledge

Yesterday, Mr Newman also made a regional announcement continuing a focus on resource infrastructure.

He began his day yesterday on ABC Radio in Brisbane explaining his credentials to run the state.

"I don't like to sound like an egotist, but I am better qualified than anybody down there that the Labor Party's put forward," he said.

Mr Newman then headed west to Toowoomba on the state's Darling Downs.

He pledged $285 million over four years for regional roads.

"A very significant boost to funding for the regions," he said.

He says it will be used for more overtaking lanes, bridge restorations and improvements to road surfaces.
