This project has strong parallels to the Wonthaggi desalination plant.
Preliminary work had started before an election, but the Liberals and Nationals promised that it would stop if they won that election.
When the Coalition won the 2010 election, they ordered work to stop, but on examining the contracts, it was found that the penalty clauses and other contractual details made the cost of abandoning work so expensive, that if they abandoned the project, they would have to pay most of the cost of the plant and get nothing in return. So effectively
, it wasn't possible to cancel it.
Now, while the stage 1 of the East-West Link is a smaller project,... IF
the former Coalition government was as clever as their ALP predecessors and they copied the penalty clauses from Labour's desal contract and put them in the East-West Link contract, then it might be (effectively) impossible for Labour to get out of the project without paying the bulk of the cost of the project to contractors too.
So just like the Wonthaggi desal went ahead despite the wishes of the incoming state government, once all the hype has died down, I reckon the East - West Link will go ahead too.
