Appreciate the responses.
Considering IXJ for their global exposure, also note that recently Macquarie recommended three healthcare stocks as an outperform: CSL, RHG and ANN.
I've been a long term holder of CSL so already have some exposure to Aussie healthcare so leaning towards IXJ with a small parcel of ANN - I did also sell my original NAB holdings keeping only the DRP shares as a free carry.
