Thanks Ozzie, i went looking for silicone trivet mats but only found a silicone mesh drain mat at kmart ($5) (and 2 cork pot trivets $5)

- silicone drain mat Kmart
Checked out the new ALDI store

It was packed full of people, and small in floor area, quite a differnet experience from the duopoly. Found a good "special" , three pack of flexible stem refillable BBQ gas lighters for $10, they're like mini blow torches with adjustable output too.

Should be good to light the Bonetti CAN stove. (and my 1985 Coleman kero pressure lamp, 2nd hand, for camping/cyclone disasters etc)
Finally found some 6pack CORK tiles at B's (6 for $17/ 0.5m2) Theyre 305x305x6mm. Reading up cork has good fire resistance and heat insulation properties, it is also impermeable to water plus a bit flexible and springs back. Amazing stuff. Didn't realise it's the bark of the cork oak tree mostly produced in Portugal, Spain and Nth West Africa. They harvest some off part of a tree every 9 years only, the tree can live to 200 years old, very sustainable. It's mostly used as corks for fine wine bottles, the offcuts are glued up to form cork sheeting and tiles. The tiles i bought are floor tiles, they have allot of wear resistance and that bit of give so peoples feet don't eventually pack up like on ceramic/concrete floors. (might be a good I563 floor covering? remember some 1970's home built yachts had them on galley floors etc)
The silicone mat should still be good for some applications, just need to find some and experiment a bit. It would creat a great non-skid surface too making it safer to have hot pots in close proximity.
