[Pil-pc-oceania] Sydney bio-region / food production

[jedd]

 Greetings,

 The ABC ran a story a couple of years ago:
 http://www.abc.net.au/rural/content/2005/s1525490.htm
 
 ... that asserted that 90% of Sydney's fresh produce was
 grown in Bringelly.

 This seems an astonishingly unreasonable figure, even for way
 back in 2005.  Can someone point me at some better and/or
 more recent statistics for Sydney?

 taa,
 Jedd.
