Please consider how YOU can help us today.

Volunteers! We are a volunteer community action group working to conserve and improve the natural local environment, and to inform and educate our members and the wider community about natural history and environmental issues. THECA provides many opportunities for volunteer work, from bush rehabilitation to wildlife monitoring, assisting with office work, creating displays, staffing the centre, or participating in a special project – follow your interests!

Sponsors. As a community group, we wish to keep our membership fees and charges for community activities low. Brisbane City Council supports us through their grants program – for example currently they contribute towards our administration costs and most recently provided a grant for funding of our new website. To cover expenses such as building maintenance, newsletter production and project costs, we need additional funds. Both one-off and continuing sponsorship are welcome – for example support for the colour pages of our newsletter, or for our ForumSee our list of sponsors.    SPONSOR US
