THE State Budget will take pressure off local families by scrapping the compulsory ambulance levy from household power bills. The cost of electricity is set to rise about $120 for average families from July, but those increases will be mostly offset by the $113 saving announced yesterday. The measure will cost the State Government $700 million in revenue over four years. Premier Anna Bligh said the ambulance service would remain free for all Queenslanders and a raft of other savings would help improve the cost of living. Electricity rebates for seniors and pensioners will be increased 6.6 per cent to $230 and the councils rates rebates for pensioners will be boosted to $200.
