From the form it looks like it's a hybrid tea rose. There are a number of yellow/orange blends so more pictures would be helpful. Photos of all stages from bud to fully open plus leaves and canes may help narrow it down.

What is tough is that there are a lot of cultivars available in Australia many rose forumers may be unfamiliar with. You may also want to post a link to this post on the Australian gardening forum. .

Here is a second shot of it. Hopefully there will be a third shot.

Can't remember how to do multiple shots, not to worry, here is the third shot.
Thanks Hoovb will go there as well.
Seil, I will get some more of it with all the bits.
