Thanks boss.  Was pretty sure they were.  Some fantastic plants out here!  Huge!  Heaps of old fallen and recently fallen trees.  Landowner also clearing fire trails snaps saplings so spoilt for choice.  
 

was reading recently they mainly press by suckering too which I didn’t know.

 

thanks for your input freakosystem

Shit!  Where did everyone go?  This place is quiet now!  Must be getting old.  I’m pretty sure they are obtusis anyway.... it’s just been a while and I hadn’t found them as big as they are here before .

"Obtusifolia" = obtuse + foliage = blunt-leaved.

To my (inexpert) eyes, the tips of these phyllodes look rather sharp. And long -- A. longifolia?

Keep an eye out for flowers and seed pods, for a positive ID.

Not flowering.  I believe longofolia are flowering now.  Obtusi’s flower dec - feb.  Also Phyllodes are tough to the feel not soft like I believe longifolia are....

 

here’s some more photos... this one is like the ones I used to find I.e very young

Yeah, wow! I’d only really found the younger ones that seem to have the thicker wider phyllodes, (to around 2m in coastal hinterland - thousands In regrowth where fkn loggers had been thru). Certainly some old examples here, I’d guess at around 4metres. Quite a bit of the forest hasn’t been logged here so mainly prolific around riparian areas, edges of the forest etc.  

 

These are also toward the extent of Obtusi’s western range and are obviously frost hardy, temps here getting down to -5 in winter.

 

Thanks for your input teamwhy

Certainly does JR.  I’ve got my eye in now.  Such diverse qualities to the plant.  From the deep dark green thru to almost purple brown then the reds and yellows... all the same type of plant’s phyllodes.  Beautiful!  
 

Your plant is certainly benefiting from a lot of love and water.  Lovely looking plant ❤️

One of the identifying features that may help you differentiate from the many lookalikes (esp when not flowering) is the reddish leaf margin when held up to the light, which you can see really well in @rottenjonny's 3rd photo. 

Nicely done!

Run your finger along the margins of obtusifolia phyllodes. You'll feel a characteristic rough, almost serrated edge in comparison to longifolia which will be smooth as a baby's proverbial.

And yes, you can often see a red crusty outline on them.
