I picked some up last time around it was floating around at Dan's. I've tried a bottle, and was interested in your thoughts about whether it still needs a bit more time laying down or did i not decant it for long enough!!
Dan's in Parkdale had 30% off stock they are discontiunuing. Lots of Riseling, few internationals (not well versed here), but they did have a handful of:
2013 Grant Burge Shadrach - $60
2015 Woodlands Russell Cabernet Sauvignon - $79
My only other thought was it could be Hart of the Barossa 2013
