Queensland children living in major centres such as Townsville would be subject to a 10pm curfew under a Liberal National government.

Opposition Leader Tim Nicholls was set to announce the plan in the north Queensland city on Thursday as part of a strategy to reduce crime, ahead of the November 25 state election.

A key measure is to ban children from the streets after 10pm, according to News Corp.

Mr Nicholls will also hear from residents of Townsville, who are struggling with a slump in employment and high living costs.
