Well this one for me is easy. Set aside bass for the time being. Ask yourself, other than bass, which ones give me that magic sinking into the music feeling? Those are the ones you get. Even if they are the ones with the worst bass. Even if they are the ones with the worst bass by far.
Why? Well because number one, the bass you actually get in your room can be a whole lot different depending on how you set everything up. Could be a lot worse. Could be a lot better. Real hard to know unless they will let you bring a pair home to try. (Which you should always ask and try to do with everything all the time by the way!)
But mostly because number two, your best bass by far, the bass that is gonna make you happy now and forever, is gonna involve not one sub (which never really works) but four. Which best of all for your situation those four can be DIY from some place like partsexpress.com or four of whatever subs you can get a good deal on.
What almost nobody understands is that bass reproduction is so completely different than the higher frequencies that the quality, size and location of subs is a whole lot less important than number. Use four and you will be happy. So leave that for later.
Incidentally, I don't know the prices in Aus or if you're looking new or used but a quick search would seem to show the price differential from your cheapest to most expensive option is about as much as a good DIY 4-sub Swarm distributed bass array. In other words if you like the midrange-treble of the cheapest pair you could afford those and the Swarm and have the best of both worlds.
I just built mine using four of this exact 10" driver which right now includes a precision cut cabinet for free https://www.parts-express.com/morel-ultimate-uw-1058-10-subwoofer--297-130 together with the Dayton SA1000 amp and you will not find better bass on Aus!
