Not much redemption availability on BA as only single daily SIN/SYD. If you just want a cheap one way J on this sector, it may be worth looking at buying AS Miles at around 2c/mile and then can use 65K+$80 on SQ. SQ has good award availability on this sector as 3+ daily flights inc A380 - can check on AS website.
If you have a sense of adventure, AA sometimes offers J award availability on FJ SIN/NAN/SYD for 40k miles.
