Hi @Curiosity, great observational notes and you are correct re the species. Could you remove images 2-4 and make a new sighting for them please? Image 1 looks to show a female laying an egg (Lomandra longifolia is the larval food plant) and is supported by your note on same while your note on images 2-4 is of male territorial behaviour.
It's a pleasure doing this job @owenh - remember if you don't agree with any of my suggestions, please help me improve by confirming the correct species.
