I don't think it's that easy for Aussies bro. Anything above 150 is a very tough one to chase in 4th innings. They have to bat their skins out to get it.
230 would have been great score 188 is 50 runs less AUS is in commanding position as of now hope Openers are removed quickly with in first 5 overs by Pacers then Spinners will dominate Middle order.
