NSW pulls rabbit out of hat on WestConnex legal mandate

WestConnex is a complex project, including new roads, expansion of existing roads, toll points, interchanges and tunnels.

The NSW government has made a surprise appointment by tapping law firm Allens to assist with an auction of its $16.8 billion WestConnex roads project. 

Street Talk understands while the unusual appointment shuns rival law firm Ashurst (which conducted the scoping study), it may still deliver Ashurst a limited role in the sale process. 

Still it's Allens that lines up with investment bank Goldman Sachs to manage the WestConnex auction

The firm's front-and-centre spot on the ticket would have been helped by its role in advising the state government on three bumper divestments of poles and wires assets. 

The last was the $7.6 billion sale of a 50.4 per cent stake in Endeavour Energy to Macquarie's infrastructure arm and partners including AMP Capital.

The NSW government wants to sell at least a 51 per cent stake in the WestConnex project before construction of the third and final stage begins next year. 

It's understood the sale process - which bankers expect to be worth more than $10 billion - will be up and running later this year. 

Banks and law firms are looking to align with bidding groups to ensure they have a role in the auction. Listed tollroad owner Transurban Group has already flagged its interest.
