0 have signed. Let’s get to 7,500!


For info on Mirvac's new plans go to   

There's 35 more reasons to SAY NO TO MIRVAC plus there's a lot more three-storey housing on 86m² micro-lots instead of the two-storey houses they had before. 

You can make an additional submission on the new plans direct through the 'Take Action' tab. Just copy and paste anything from the 'Latest News' tab and include it in your online submission.

If you've made an objection before, just include the words "Additional submission".

 Below is prior to above update:

ForestinDanger sent a letter to the Department of Planning, Ministers etc telling them about the Koalas on the site.

They have ignored the letter. Please help us SAVE SYDNEY'S KOALAS.    

This development must not proceed.  This is last remaining Koala population in the heart of suburbia.

The NSW Forestry Corporation recently released its "Forest Management Plan outlining management of Cumberland State Forest". Page 15 of that report states that Koalas (Pteropus poliocephalus) are "KNOWN TO OCCUR WITHIN AND ADJACENT TO THE CUMBERLAND STATE FOREST".

Please sign and share.

For more information please go to ForestinDanger


Hills Shire Council has drafted a shocking new section in its Development Control Plan specifically for the former IBM site to allow one builder, Mirvac, to create micro-lots of just 86 sq metres on the ForestinDanger site. What a terrible precedent to set for the Hills Shire. These Mirvac mouse-houses won't even have room to swing a cat. More traffic, 2,000 less trees, miniscule blocks of land, special site provisions for Mirvac. 

What's to love about this proposal?

And Mirvac is insulting enough to say West Pennant Hills is "in the middle of nowhere". 

GO HOME MIRVAC. The leafy Forest Valley doesn't want your insults or your developments.

Read about the proposed changes in the new section of the ForestinDanger website once read there is the option to take action by going to the header of the page and clicking "take action".

Earlier petition information (including prior petition):

Mirvac has a development proposal in progress to rezone more than 28 hectares of heavily forested land adjoining the Cumberland State forest to allow for 400 apartments and 200 medium density houses. I am but one of the many residents who cannot stand by and just let this happen, as once this forest is gone it cannot be replaced. Please take the time to read the following information.

The proposed rezoning is to allow apartment dwellings on the entire site with no protective environmental zoning for the critically endangered Blue Gum High Forest or endangered Sydney Turpentine Ironbark Forest, that covers the majority of the site.  It will destroy habitat of the protected Powerful Owls that are on the site.

Objection to Mirvac development application for 55 Coonara Ave, West Pennant Hills NSW

I am opposed to the proposed amendment to the Hills LEP to allow for medium to high density development at 55 Coonara Ave, West Pennant Hills. It allows 400 apartments and 200 houses built by Mirvac on land currently zoned B7 business park.

A significant part of the site is covered in critically endangered Blue Gum High Forest and endangered Sydney Turpentine Ironbark Forest. Appallingly no protective environmental zoning has been proposed. Powerful Owls which are listed as vulnerable species are found on the site. The development would destroy their habitat.

The proposed development also lacks infrastructure and amenities, with most of the site a steep walk more than 800m from the new Cherrybrook station. An extra 600 dwellings will add to traffic gridlock on Castle Hill Rd, Highs Rd, Taylor St, Aiken Rd and Oakes Rd.

Most of this land should be rezoned as E2 environmental conservation with protection for mature trees on any part of the site used for residential. We want this beautiful forest protected not bulldozed for high-density apartments.
