This is a highly significant record; the closest record is located near Taree NSW. This species appears to be expanding its range in Australia since arriving in northern Australia in 2012.
User's notes
I first observed this butterfly flying to a rose from a distance, and I came closer and did not know its species, specualting relation to the Glasswing. It flew onto the grass, and I ran and took a photo, before it flew with another individual and later flew over the fence with one more individual.

Great sighting, memo to naturemapr, Is this an exotic species if it got here by itself, which it seems to have, starting in Darwin in 2012, and it has a wide distrubution in our near north.

Doesn't exotic just mean it's not a native - eg same as the Monarch (Danaus plexippus) on Naturemapr.

No, quite different, this appears to be a naturally self introduced species which as been spreading towards us through SE Asia for some time. Its main known foodplant (Hybanthus enneaspermus) is native here, and is also widespread in Asia. Yes, it is not endemic to Australia. Its in the same boat as many other species, esp. in northern Australia, like many swallowtails, and nymphs that have widespread distributions in SE Asia as well as being found here. The only difference is that here we have seen the process of arrival happen. That being the case it is (now) a 'native'. Its certainly not an introduced species reliant upon introduced plants to survive. An equivalent in the bird world it would be the Spotted Whistling duck , which has recently moved into FNQ from New Guinea. This is part of the natural flow of life and should be treated as such.

Conservation level setting for the species best passed on to Drs Mulvaney and Bond @MichaelMulvaney @SuziBond methinks.

Vagrant or cosmopolitan may be the best way to describe this species

I thought vagrants was usually applied to non-breeding species that arrived under their own volition. There is a constant 'rain' of insects migrating downwind into northern Australia during the NW monsoon and in the same way Australia exports many vagrants to New Zealand each spring on prefrontal airflows, most of which do not establish because of lack of host plants (the vagrants). A different example would be the Fall Armyworm, Spodoptera frugiperda, that migrated from the New World to Africa in 2013, spread through Asia in the next decade and arrived in Australia in January 2020. Although it's a pest of introduced crop plants, the larvae also feed on a wide range of other native plants. So I would consider it a recently established cosmopolitan species. The Monarch Butterfly is an anomaly since it has followed the spread of its introduced larval food plant (milkweed, Asclepias) across the Pacific by natural migration and has been in Australia for 150 years.
