Thank you, Kiwibird! Is newspaper lining appropriate for lorikeets, too? I use newspapers for the bottom, then corbo to absorb the water (lorikeet droppings are really watery) and there's a grate over that where he can stand on. But maybe just the newspaper and the grate would do it?
I see no reason why newspaper would hurt them, but if they have liquid poops, you may want to try a different method because it might corrode the cage bottom (hopefully other lorikeet owners will weigh in on this???)
Do you know how to sew (or anyone who can?). If so, these are SUPER easy to make and the best cage liner I have ever used. I personally have to use washable cloth cage liners because Kiwi takes daily dish baths and I need something absorbent because newspaper didn't work (rusted the bottom of his cage within a couple years). I use ripstop nylon on the bottom (which is waterproof and keeps it from seeping through), a layer of batting in the center and flannel on top. I've been using them for over a year now, change them every other day, scrape/shake them off outside (to get off the big chunks), spray bacout on any stains (where the poop was) and wash them in their own load every week. They work wonderfully and I have had no issues with smell or rust/corrosion of the tray of his new cage.
This is how it's layered:
How they look finished (the one with the "hole" is for his play tree):
This was in his old cage, but they go on the bottom just like newspaper
This is the material (for the absorbent layer) you might want to try for a liquid pooper. It's made for cloth baby diapers and is highly absorbent/designed to be soaked with poop/made to be easily washed:

Ripstop nylon and flannel can both be found at any fabric store.
This stuff can be found at most "natural" stores, but it's cheaper online:

As long as you spray the liners with it after you clean off the "big chunks" it prevents stain and smells from forming before you wash them, again another product people use on cloth diapers, so it is 10X as effective on low-no odor parrot poo
