Experienced in the related fields of the Public Works Act and the Local Government Act, Bianca can help with public acquisition, development contributions and private development agreements.  She provides clients with valuable continuity between Notice of Requirement and acquisition processes on significant infrastructure projects.

Clients also seek Bianca’s assistance with undertaking environmental due diligence.  Her expertise in this area includes advising on the Overseas Investment Act (OIA), contaminated land liability, and drafting environmental warranties and indemnities.
