More than half of Queensland is now officially in drought after two more parts of the state were drought-declared on Friday.

Parts of the Balonne and Maranoa Shire in the state's south-west were confirmed as drought regions by the state government, bringing the number of drought-stricken shires to 20.

Agriculture, Fisheries and Forestry Minister John McVeigh said those shires as well as individual properties and other council areas meant more than half the state was now in drought.

"Nearly 52 per cent of Queensland is now drought-declared, underlining just how serious the situation is," he said in a statement.

He said affected producers could apply for government assistance and encouraged other primary producers who believe their properties are facing drought conditions to contact authorities.

"The Queensland Government will provide up to $20,000 to drought-declared producers each financial year," he said.
