Not a happy lopper. Went into an area that I have not wandered into before to lop wattle and came across these little invaders. Need confirmation that they are what I think they are before I start to erradicate them :)

I'm thinking this is a bottle brush of some kind. Don't care if can only get to genus level as I just need to know it it not native / endemci they it is coming out! Only found 2 in this area so will be be a big job to erradicate :)
