I had already thought of using Sorbothane and had contacted Australian supplier but the only thing they have is 1" sheet and they want $400 for that as well.
So much for cheap TR.................
I don't know what supply houses are in AUS , but you might be able to find something in an industrial supply catalog or supplier . https://www.grainger.com
is one here in the US that might have bumpers or pads for industrial equipment that may suit at a fraction of the cost of products intended for audio or space shuttle equipment , as Sorbothane says their product is used for .
I picked up these rubber stoppers at Home Deopt in the specialty bolts and pieces bins in the hardware section as a temp solution until I have a few more things for an amazon order , and they are decent at least . Cost about 2 bucks each .
Just had a thought , has anyone looked into coil springs or little airbags for the decoupling ? I know coils would be tricky to get right , but don't know if it's a supid idea overall , for airbags I saw some little airbags for lifting and adjusting heavy items at Home depot , they inflate with a little bulb like a blood pressure cuff and say they can lift 300# each , so should be strong enough to last .
Edit: decided to play hookey and go buy another driver , and swung by the local Grainger . The only isolators that they could come up with a durometer rating were at 50 , so not close to the 20 the OP suggested , back to the drawing board there.
2 other possibilities I thought of . 1) my friends kid used to play hockey in the house , had a really soft , air filled hockey puck . Going to try to find those , if I remember the air was sealed in , but it was fairly easily compressed .
2) thought about wheelbarrow or hand cart pneumatic tires , or just the tubes . they are 8" or 10" diameter , and obviously adjustable depending on air pressure . A friend has a few hand carts at his shop for order picking , think I'll break in in the next couple days and "borrow" a few and see if the air ride suspension idea will work
