I'm smiling here by my own because looking at your photos I wanted to say it looks like autumn, then I've checked out where Mt Lofty is exactly and bingo! 😁 Although the cute kangaroo led me to believe I'm right.
After a long and gray winter (I live in Europe), it's nice to see so much green ans do many beautiful flowers in one place. Some of them are known to me, the others are new to me but they are all very nice. You've managed to take some amazing photos, congratulations!
