Wattle tree now in flower. (Acacia)

Out the back of K's place, the wattle tree (Acacia) is finally getting to be a nice bright yellow/gold. But I don't know which Acacia it is. Don't have my Wild Flower book of Australia with me.
Been out digging today, not a lot of luck. Had to go into Emerald this afternoon to get fuel, groceries and pay for the ambulance that took PJ to hospital, but got there just after 4.00pm and they had SHUT at about 2 minutes past 4.00pm!! Will have to got into Rubyvale tomorrow and do it there. (Hopefully)
