The NSW government will be able to keep secret intelligence it has gathered on suspected terrorists under new laws coming into effect on New Year’s Day.

From January 1, the government will have the right to apply to the Supreme Court to protect information on accused terrorists from them and their lawyers.

The measure is part of new anti-terror laws introduced to parliament in November, which also gives law enforcement agencies the right to use surveillance devices in prison cells.

A host of cost-of-living measures will also come into effect in the new year, including the state’s new ‘baby bundle’ and 10 days paid domestic violence leave.

However the new year will also mark a toll hike for Sydney motorists, with a trip on the M4 rising to $4.93, while the Hills M2 will go up to $7.42.

More than 300,000 drivers will be eligible for half-priced or free registration based on their toll spend, but they’ll have to wait until July to earn their savings.

Changes to the state’s fair trading laws were also introduced in late December, making it easier for consumers to deal with defective gifts.

New laws will empower the Fair Trading Commissioner to direct traders to refund, repair or replace eligible goods.
