I'd wait for the fed govt rebates to come in. The blow in insulation will settle, and I believe there are issues with it, if you have a house on piers (ie, you need to seal the bottom of the walls. All insulation will settle - batts (pink or otherwise) will squish down over the years - the insulation level is dependant on the air pockets - so the fluffier/fatter the insulation, the higher the R value. Of course pink batts or polyester batts you can put in without protective clothing - but with the fibreglass batts, you need to cover everything with protective clothes, as there are small fibres of glass, which irritate the skin and are terrible to try and clean up.
There will probably be a lot of people waiting for the insulation rebates, so expect a delay in installation, but the benefits will mean you pay less to heat and cool your house, and you'll find the house much much nicer to be in.
