Premier Anna Bligh will float the idea of an increase to the existing $7,000 grant, to be called the Regional First Home Owners Grant, at a lunch hosted by the Property Council of Australia today.

She will argue the cash incentive - which could be made availabe by January 1 - would help bolster regional economies in Queensland, pointing to the Henry tax review as the motivation towards decentralisation and regionalisation.

Queensland' s population surpassed 4.4 million last month, with much of the new settlement occurring around Brisbane and the south-east corner.

While the population boom synonymous with the middle of the decade may have abated marginally, 383 people a week are migrating north from southern states in search of sunshine and a sub-tropical lifestyle.

A further 1011 people are moving to the sunshine state from overseas each week.

In the past year, 52,6000 people moved to Queensland from overseas countries making for the highest overseas migration rate since 1971.

Ms Bligh has said an extra cash bonus to the first home-buyers grant could encourage more people to build new houses in their home towns rather than leave for the big smoke.

The additional bonus would be funded by the State Government, which says it will also turn its attention to boosting infrastructure and services in regional Queensland.

Ms Bligh will tell the audience at today's luncheon she wants a "conversation with Queenslanders" on how to encourage decentralisation and regionalisation.

"Should we have new policies to create incentives for more people to settle outside southeast Queensland?" her speech notes say.

"Should we consider, for example, a new Regional First Home Owners Grant, set at a higher dollar value - say $3000 more?

"It could be directed to new construction, to help stimulate regional jobs."
