Queensland, Australia
There where multiple of them not seen in the picture so the spider seems communal, I had seen up to 5 of them at one point
Couldn’t get a clearer picture because it’s been raining on and off and I didn’t want to get my hands and phone near an unidentified spider
Tried googling but couldn’t identify it
Edit: I’m also pretty sure it had caught an insect in this picture
I’ll throw my hat into the ring and say it’s an eastern bush orbweaver (Plebs euburnus).
I remember the scientific name because it sounds like: plebs? Ew! Burn us!
Should have a U-shape white marking with 2 additional spots on the abdomen. They prefer scrub and tall grasses, nocturnal and tend to hide behind leaves (or in this case, your curtains) during daytime.
(AFAIK) Not aggressive and prefers to run away rather than bite.

If you’re in Western Australia then maybe it’s a Plebs cyphoxis and I couldn’t see well the coloration, but it seems to have the humps.
In either case, you should check if its web has something like a zipper (stabilimentum): https://www.arachne.org.au/_dbase_upl/Araneus_cyphoxis_D5991_Z_87_Warren-National-Park_Australie.jpg
