Newcastle's first ever Better Block project is coming to Mayfield in May! 

THE KOPPERS Australia plant in Mayfield has become the focus of an investigation into a series of strange night-time odours in the suburb last month. 
Dozens of residents took to social media to complain about the mystery smell over a week in March, described as being similar to chlorine or sulphur. 
The smell was most pungent at night and could be detected as far away as Carrington and Waratah.
