Thanks Rob & Justin.
Rob - I wasn't sure at first, but I searched for lots of zodiacal light photos on Google Images, read a few articles, etc and I'm convinced that's what I've captured. The yellowish "star" in the top-left corner is Saturn, so the light follows the ecliptic.
Justin - Brisbane weather has been horrible lately. I drove 6-7 hours west for those shots to escape the SE QLD weather system/area... dark skies were a bonus
