Zero. I transfer my points (Amex 7 Westpac) to SIA, a superior airline,

I will take my chances leaving the points in my Amex MR account and decide where to transfer them if and when I need them....
That is the risk that one would have to weigh up when making a decision to travel with another alliance. If travelling in WHY to/from major airports then theoretically one should still be able to get lounge access with Platinum status. If booking early enough one may also get a preferred seat pre-allocated or spend some extra money and pay for exit row.I guess the issue with flicking points to SIA for hard core OW fliers like you and I is that you miss out on the soft (or indeed hard) benefits of being a status flier - especially if flying in whY.
The last I would want is flying for better value on SQ but getting stuck without a lounge, priority boarding etc... not such an issue for my parents who will be beneficiaries of my MR points as a free trip is better than no trip...
If there is a significant saving in points required then one may also be able to travel in a higher class and get lounge access that way. Just looking at current SQ specials one would require 67,500 Amex MR points + taxes and surcharges for SYD-SIN-BKK return in business class or 41,250 Amex MR points + taxes and surcharges for a SYD-SIN-BKK return in WHY whereas 60,000 Amex MR points + taxes and surcharges are required for a SYD-BKK return in WHY.
I've just noticed that QF are runnning the campaign "Time to Choose" on their website:
