The more you research, the more writing residencies you find in Australia. It is a pity, however, that they are not all included on one website. Some go it alone, while others are registered under ResArtis. Failing that most retreats are in the middle of the woop woops, rural bush retreats, out of the way, and there is a reason because they provide the quietude any artist needs. The only problem is, often they are fairly inaccessible and you need a hire car or require help with a lift from your host.
One such Australian Residency Network exists under the banner of BREW. No, this is not a brewery or a pub crawl, it stands for Bush Retreats for Eco Writers. And there are 5 all told: Blue Bucket, Tamborine Mountain, Burrabungle, Plumwood Mountain and Pinchgut Creek.  The good news is they are nowhere near “Wolf Creek”. Note: Make sure to email some inquiries re accommodation. I always worry when they don’t show the internals. You may have to rough it and don’t forget the Aeroguard!

The Bush Retreats for Eco-Writers (BREW) network offers free 10-day residencies for writers, poets, students and artists who explore ecological themes. Initiated by eminent Australian environmental philosopher Professor Freya Mathews, the network currently has five sites, located on ecologically significant private properties in various parts of Australia.
With a view to fostering environmental culture in Australia, BREW warmly invites applications for residencies to undertake ecological writing, research or art projects at any one of it’s properties.
Innovative conservation projects are underway on several of the properties and, to support this work, these sites are also available as research sites to interested ecologists. Opportunities may exist to partner with local art centres and present in local schools.
Hosts offer basic self-catering accommodation. There is no charge, but residents may be asked to make a small contribution towards electricity and other costs. On some properties, residents can participate in conservation activities. Residents are asked to provide a short report on their stay to post on the BREW website for the benefit of other applicants.
More information can be found on BREW’s website.
You can also request an application form for a 10-day BREW residency, or to ask a question, via the online contact form.
