Ever since the guided rounds appeared on the scene HIMARS has been a very attractive proposition for Australia. It will be interesting to see if there is significant reserve involvement when the capability is acquired.Sorry - a multi-barrel rocket launcher doesn't fit Australian CONOPS?
As @Redlands18 said - welcome to LAND 8113. MRL has been on our list of projects for a while now. It'll fire a range of weapons, precision and other, and offer significant advantages and opportunities. Something like counter-battery fire is perfect for a MRL. It's not a BM-21, it's a significant step up in every way, but MRL it is.
