Short-horned Grasshopper

This grasshopper has been in my collection of biodiversity photos since April, 2016. Back then, when I was trying to identify the grasshopper shown here, I had some confusion between Oxya japonica (Thunberg) and Gesonula mundata (Walker), but after some considerable searching on the web, reading PDFs and comparing pictures. I decided in favour of Gesonula mundata. I wasn't entirely sure, but, at that time it seemed like a reasonable decision. When I eventually, yesterday, got around to uploading a spotting to Project Noah based on these photos, I carried out a quick check, as usual, before clicking on the "Publish Spotting" button. That was when everything was turned upside down. I looked at an article by brisbaneinsects.com, expecting to corroborate my identification, but the exact opposite happened. There is a sentence which states "We recognized this grasshopper by the banded-pattern on the antenna and its slender body." Of course, this "banded-pattern" does not exist on my specimen. So, I am back to the beginning again with Unidentified Acrididae because I cannot even be certain of the Genus now.
