Major cities are calling for a congestion tax - a charge for every car that drives into the CBD - to help ease the traffic during peak hours.
According to Tony De Domenico from Urban Development Institute of Australia this tax has been used around the world in Milan, London, Stockholm and Singapore.
"There is no reason why we couldn't put it on the table and discuss it," Domenico said.More stories from Today Tonight
Domenico blames a lack of government planning for Australia's overcrowded roads.
"There needs to be some future serious planning done. The thing I think that fails is that any money collected in that way ought to be dedicated solely for use of improving public transport or improving the road system," Domenico said.
Professor John Stanley from the Institute of Transport and Logistic Studies at the University of Sydney believes congestion charge is inevitable.
"It's the only reliable way to reduce the demand for road use without getting a bounce back effect and it's also a very effective way to raise revenue," said Stanley.
Stanley proposes a distance-based charging regime - up to five cents a kilometre in peak travel times - offset with a discount on car registration fees.
"I'd be looking at something like the Dutch plan to have a GPS based system where in fact you charge people for the distances they travel and where they are and the time of day they travel. In peak hours on trips to the CBD people would be paying more but you would have spent some money on improving public transport to give them a choice," he said.
The most congested times are typically 7:00am to 10:00am each week day morning and 5:00pm to 7:00pm each night, when roads become car parks. The cost is a staggering $10 billion in lost productivity a year and is forecast to rise to $20 billion by 2020.
According to Paul Cowperthwaite from Transport for London, the city has seen a 15 per cent reduction in traffic and 60,000 less vehicles entering the zone each day.
10 years since implementing a congestion charge in London, Cowperthwaite says it's become a way of life for locals.
"London was very lucky in that 85 per cent of people who entered London already did so by public transport. However, congestion charging has had the benefit of raising 1.2 billion pounds, which has been invested back into transport," Cowperthwaite said.
Experts believe that it works well in cities like London because of exceptional public transport. Still, there are mixed reviews on its success from the people of London.
It may not be called a congestion tax but councils and state governments are already forcing cars off the roads with the installation of bus and bike lanes to discourage drivers from entering the CBDs.
In Sydney, what amounts to a congestion tax is already being charged, for instance travel on the Sydney Harbour Bridge and Harbour Tunnel in peak times and you'll pay at least a dolalr more per trip. There is a levy on car spaces in privately owned car parks - $2100 per car spot, per year in the CBD and North Sydney.
In Melbourne, 60,000 car parking spaces will be subject to an increase in congestion levy tax - up almost 40 per cent to $1300 a year per spot, per year. Car park operators say they will pass on the increased cost to drivers, boosting the government's bank balance by $44 million.
Brisbane drivers have so far escaped a levy on car parks but with the financial collapse of the Airport Link, congestion tax is back on the agenda.
Russell Zimmerman from the Australian Retailers Association claims this will stop people from going into the city and spending.
Zimmerman fears slugging shoppers will drive money out of the CBD.
"If you're coming from somewhere like the Hills district in Sydney where there's no public transport, that would be a huge impediment to coming into the city," Zimmerman said.
It would be a brave government to introduce a congestion tax but the number of recommendations is piling up, as is Australia's population.
