Can anyone ID this Acacia?

Hi,
Can anyone please ID this Acacia?
I live in adelaide, SA, and there are a fair few of these acacias around the streets where i live. I tried to figure out what it is myself and am convinced it is an acacia retinodes. Can anyone confirm this, or tell me if i'm wrong?
thankyou.

 

I'll second your ID of A. retinoides - it's a popular boulevard tree here as well.

 

thanks lorax
