After a quick look at the tent (online), I can offer a couple of things to consider. Yes, it's comparatively heavy but certainly low cost. It would be OK for QLD & NSW.
It doesn't have a vestibule so all your gear, packs etc, would need to fit
in the tent with you - tricky in rain as all the gear is wet.
The door design doesn't stop rain from entering the tent (if door open for ventilation or when getting in/out).
Rain is a bit of a focus for Victorians - maybe in sunny qld it's not an issue
