The new financial year brings a raft of changes in New South Wales, including the end of cash-tolls on Australia's motorways and a bump in gas and electricity prices.

Australians have been fumbling in their glove boxes for change to pay tolls since the first motorists on the Harbour Bridge paid six pence in 1932.

However, overnight the last booths were removed from the only toll road in Australia that was still accepting cash - the M5 in Sydney's south west.

Now all motorists will need to pay their tolls electronically - with an e-tag or e-pass - but there will be no change to the price.

The same cannot be said for gas and electricity.

As of today gas prices will increase by an average of 8.5 per cent and electricity by 1.7 per cent.

In transport, Railcorp is being officially split into two entities, meaning Cityrail and Country Link will be now officially rebranded Sydney Trains and NSW Trainlink respectively.

Learner drivers are now able to drive at a maximum speed of 90 kilometres per hour, up from 80 kilometres per hour.

L-platers can also reduce the number of log book hours needed to qualify for a provisional licence to 100 hours by completing a government safe driver course.

And fares are set to increase for taxis this month, but not until July 22nd.
