What we know about Qld's 2017-18 budget

What's in store in the Palaszczuk government's third Queensland budget.

ALREADY ANNOUNCED

* $400 million boost to concessions to ease pressure on household budgets, bringing total household concessions up to $5.3 billion

* $155m for 50 extra police (30 counter-terrorism officers and 20 frontline police) as part of an anti-terrorism plan

* $1.8bn over 10 years to build 4522 social homes and 1034 affordable homes across the state.

* an extra $200m over four years to improve child safety, with a focus on domestic violence and ice addiction.

* $500m for two new high schools in inner-Brisbane and the upgrade of West End state school

* $386m investment in electricity, including $150m for renewable energy projects and $200m for a hydro-electric power station at the Burdekin Falls Dam.

* $770m to fully subsidise the cost of the Solar Bonus Scheme.

* $15m Whitsundays airport upgrade

* $20m to employ an additional 20 Queensland Boating and Fisheries Patrol officers

THINGS TO LOOK OUT FOR

* tax increases or cuts.

* whether or not there will be an operating surplus as tipped. A mid-year economic review forecast a surplus of $2.03bn, the largest in a decade, but that has taken a hit from the cost of cyclone Debbie recovery.

* funding for Brisbane's Cross River Rail project. The government has yet to reveal whether it will go it alone to start work before the end of the year after the federal government delayed a funding decision.

* any government borrowing to fund its measures which potentially has an impact on the state's credit rating.
