The Australian guidelines are due for a refresher. The current version is from 2006 \cite{16618231}, with a significant addendum added in 2011 \cite{2011}. This guideline still includes new LBBB as a STEMI equivalent, and does not include the Sgarbossa criteria.
As mentioned above, the 2013 ACC/AHA guidelines have removed new or presumed new LBBB as an indication for PCI, but also do not include any of the Sgarbossa criteria \cite{O_Gara_2013}.
Which leaves me with a final question... is it a STEMI or a STEACS?
