The Australian high-end resorts certainly aren't for everyone. For example every Oscar nominee gets a stay at El Questro (worth $12,000). Now is it worth $12,000 when some guests stay for free (never mind that it is Kate Blanchett next door)? Along with stunning scenery and generally decent food and wine (maybe better than you'll get at those great value SE Asian 5-star resorts). Saffire/SOL/etc. are definitely not mass market, priced to keep it that way, and one-of-a-kind in the world experiences. Highly cost effective for some, a waste of money for others.
As for the OP's desire for hints and tips, you won't get much that is useful on FT. I haven't stayed at Saffire yet, but love SOL, hate Qualia ... so shows you how fickle it can be. Chartering a plane is pretty cost-effective for SOL to Saffire transfers, fwiw. I've had good luck with
