It appears to stack with 5% off https://www.ozbargain.com.au/node/195434 promo code AUEUR14 but when I tried it it only reduced $618 fare down to $614. I can't be sure if this will work because I did not progress to the payment page, at which time it 'could possibly' be rejected. Sydney to Singapore was with Qantas. I did not try the other trips.
