I feel your pain Mal, The M4 in Sydney has a toll on it again starting from today. Another toll road originally a freeway that was paid off a few years ago AFTER having tolls imposed on the taxpayer / motorist funded section for about 20 years !This is the 2nd time this has happened on the Parra to Homebush section of the M4.As guessed, heaps of cars turned off to use Parra Rd to avoid the toll. The resulting traffic Jam was better than the one on the M4 cause they weren't paying to sit in this Jam. !! 
Enough Bitching.
 Good on John Cowper for his win in the New Tram sneak peek competition. I wasn't surprised to see his name amongst the winners !
Regards,
Tim, in Sth west Sydney (miles from the M4) but a previous user.
