There is no winter in SydneyA chilly winter's night of 9 degrees Celsius here on the coast, prompted me to look at Trove for postings about winters in the past. Having lived in Sydney for 11 years in a past life and now living in a even milder climate, I have some empathy with this author's sentiment.
Here's a section of the article from The Evening News in Sydney, 4th June 1904. The author further continues the article and posits that one must venture further afield in NSW to experience a winter more akin to that described by Keats.
