'Readers of this issue of the Journal may notice some changes to the style and format that have been introduced. The changes are quite minor but have been made for two main reasons, following extensive discussion with our New South Wales colleagues. First, there are changes that will bring both the Melbourne and Sydney editions in line with the format of similar publications. The changes include use of abstracts and keywords - as explained in the new comprehensive Style Guide, accessed from the link inside the front cover - which will aid the digitisation and on-line searching (and reading) of the Journal in future. The second reason for the changes is that the slightly different format will enable substantial savings in print costs, always a worthy endeavour! Plaudits to Louis de Vries of Hybrid Publishers for his input and advice regarding the new format, as well as for his help in other ways. ' (Editorial introduction)
