Seems to me, getting a 457 visa might be a good interim measure. I'd guess any Ramen shop would be able to help out with that and we're happy for them to (continue) living with us indefinitely. As her tourist visa runs out shortly I'd like to offer this suggestion - but at the same time don't wish to interfere in their deliberations. She's certainly a more legitimate 457 applicant than so many "engineers" driving trucks for mining companies now.

Any informed suggestions gratefully received, thanks Felix.

If the ultimate goal is being able to live in Australia permanently, then I really can't see the point of applying for a sc. 457 visa first.

There is no guarantee that it will be granted, even if she has the right qualifications and an eligible sponsor. A sc. 457 also requires (expensive) health insurance and comes with work restrictions which could carry over to any future bridging visas.

As Wesley suggested, get them to seek some professional advice, so a proper strategy can be developed. With the current cost of the Visa Application Charges, a refusal doesn't bear thinking about.
