That totally wasn't my understanding. My understanding was:
1. sell within 12mths, you pay 100% CGT (times by your tax rate)
2. sell after 12mths you pay 50% CGT (times by your tax rate)
Looks like the market in Alexander Heights is moving pretty quickly - everything under $400k is practically all Under Offer.
Will be interesting to watch. But I can see that if you were working on $380k that it wouldn't suit your risk profile.
