hello,

oh wow that is nice, i will say I don't know what it is, but is it growing in a desert climate? could it be a form of tumble weed?
maybe a horthorn? (we have them as bushes in the UK, horribly prickly.

None of the above. A member of the Fabaceae of which Australia has a huge number.

I think it may be Jacksonia calcicola, which is a member of the Fabaceae family.

Here is a link that might be useful: Jacksonia calcicola

thank you for your help, I know the park did have Fabaceae plants but had no idea what they looked like! could you help me with one more? Nobody has been able to identify this one for me, not even /r/whatisthisplant!

I think it is Melaleuca gibbosa, slender honeymyrtle.

Aerilia123 - reading you answer, I'm not sure if you realised that Fabaceae is the name of a whole family of plants, not one specific type of plant. I believe the family has over 1000 members in Australia.

If you follow susanc's link you will see the particular species within that family that she thinks your first plant is.

Sorry, if you knew all that. It wasn't clear to me from your reply.

thank you so much susan! that's it!
