Residents of Dereel that would like Telstra mobile phone service please send a letter to the Golden Plains Shire stating that you require mobile phone service (no need to go into details, a single sentence of "I want mobile phone service in Dereel" will suffice).
Post it to:
TELSTRA MOBILE SERVICE IN DEREEL c/o Golden Plains Shire Council PO Box 111 Bannockburn Victoria 3331
or you can email your support to Jenny Blake (again simply state "I want mobile phone service in Dereel" with the subject "TELSTRA MOBILE SERVICE IN DEREEL").
I have of course forwarded the community support I collected back in 2010 but more support or reasserting your support isn't going to hurt.
