Taking up any government grants is just good business practice, take for example the R&D rebate that is on offer at the moment - many profitable businesses take this up, it all adds up!
With regards to the PSF/BUD linkage - there is one thing to be 'mates' and something else to follow each other half way across the world, list on the ASX together, locate in same city & deliver systems that have a lot of synergies. This should be considered a method of 'de-risking' for both companies, if one does succeed, the other will likely be able to follow suit.
