What Tropical-looking Flower is this? (Australia)

[aRustle]

I live in Western Australia and some flowers have started to blossom in my back yard. They seem to only last a day or two before wilting and I was curious if someone could identify it. It seems to be very similar to the Rose of Sharon, a hibiscus, although I can't seem to find an image of one that looks like this.

Any help would be appreciated, thanks guys!

I looked at the image and thought of a hibiscus. But I read that you already thought about that.

Looks so beautiful though!

definitely malvaceae family. looks a little like abutilon, but not quite right there either.

Hibiscus mutabilis ???
