We're adding extra lanes to the Monash Freeway between Warrigal and Cardinia Roads to make your journey quicker, easier and safer.


We aim to have the lowest possible effect on the local environment while we build a safer and more accessible road for everyone.

As part of our planning process, we’ve completed our assessment of flora and fauna biodiversity values, Aboriginal and historical heritage, contamination and noise.

Fauna and flora biodiversity

We focused our flora and fauna biodiversity investigations on the eastern section of the works, between Princes Highway, Narre Warren and Cardinia Road, Officer.

As part of this, we found several patches of native vegetation within the eastern section of the project area. We also found habitat values for several threatened fauna species.

The native vegetation found at Cardinia Creek and Lower Gum Scrub Creek is associated with the Growling Grass Frog ponds. These were created when the Pakenham Bypass was built.

To minimise the effect of the project on these areas, we’ll make them no-go zones while we build.

Read more about the biodiversity values we found in our flora and fauna assessment  (PDF, 36.0 MB).

We assessed the western section as part of an earlier report and found nothing that requires specific environmental management

Local heritage

We found no local historical heritage within the boundary of the project. We did find Aboriginal heritage at several locations within the eastern section of the project between Clyde Road and Cardinia Road.

We’ll make sure the Aboriginal places will be protected from effects of the project.
