Whoops! Thought I was in Australian Native Forum. I will repost there, but in the meantime here is a close up of the flower. Sorry it is slightly fuzzy, but it was quite windy at the time and the flower just refused to stay in one place to have its picture taken. :-)

Myoporum sp.?

Thanks, nonmember.
That looks a better starting point than Leptospermum. Now for some research to try and get even closer. :-)
