Shellite should work just fine if you do a freeze precipitation, it's a lot more selective than Xylene though, meaning it will mainly pull N,N-DMT and very little of any other Alkaloids. The downside to Shellite is that it takes more pulls to remove Alkaloids from an extraction

Xylene's the second option but it's slow to evaporate and smells a lot more. The upside with Xylene is that it can pull and hold a larger amount of Alkaloids, meaning you can yield "full spectrum" and also extract doing less pulls.

You could also try ordering in D-Limonene online. I know very little on using it though.

Most of the other solvents that can be used are fairly difficult to come across in Australia, so your best bet is to stick with the two mentioned above, or look into D-Limonene as a cleaner alternative.
