Dubbo City Council will push the state government to introduce on-the-spot fines for consuming liquor in the restricted areas.

Offenders could pay $220 if caught, under the regime outlined by the council.

Confiscation and tip-out powers replaced monetary penalties in 2010.

The move to address what deputy mayor Ben Shields called a "toothless tiger" was made as the organisation voted this week to seek to renew the city's alcohol-free zones for another four years.

The council also proposed to add sections of Sterling and Jubilee streets to the restricted areas.

It came a week after debate in the council's finance and policy committee about enforcement and penalties for drinking in alcohol-free zones.

Cr Greg Mohr said councils should push the state government to increase the fine, which he understood was $50.

The committee recommended renewing existing zones in the central business district (CBD), West Dubbo commercial area and six neighbourhood shopping centres until December 31, 2018.

Cr Shields questioned if Sterling and Jubilee streets between Goode and Tamworth streets - areas near a neighbourhood shopping centre - should also be included.

This week he moved an amendment, seconded by Cr Mohr, to include the additions and call for tougher punishment.

Since Cr Mohr had raised the issue of penalties the previous week they had found they were even less severe than thought, Cr Shields said.

"It seemed to me and to Cr Mohr that they (alcohol-free zones) are a toothless tiger," he said.

"They need to be sharpened up."

Cr Shields' amendment was carried by the council.

Under the resolution the council will make representations to the NSW government seeking to have an on-the-spot fine introduced for consuming alcohol in an alcohol-free zone and that the fine be two penalty points under the NSW Crimes (Sentencing Procedure) Act 1999.

It will also submit a notice of motion to the 2014 NSW Local Government Conference seeking it to make the same representations.

One penalty point is $110, according to section 17 of the Crimes (Sentencing Procedure) Act 1999.

The council will cite crime rates at Dubbo, community concern over crime and law and order issues, and the low incidences of street drinking as a result of the existing zones as reasons to renew the zones.

Monetary penalties would no longer apply for the consumption of alcohol in a prohibited area, the NSW Division of Local Government advised councils in 2010 after Parliament passed the Local Government Amendment (Confiscation of Alcohol) Act 2010.

Instead, "confiscation and tip-out powers" would apply.
