Frequent flyer research - experienced travel industry person -- 2

Direct experience in the travel industry. I need research to locate ff seats. I am interested in flights on Singapore Airlines and Qatar Airlines only Ideally I want 3 seats and do not mind if one is on a different day. My priority is to get the lowest point cost seats.I am looking for business class Sydney to Tokyo on Singapore Airlines and business class Sydney to London (or any major European city) on Qatar Airlines. The travel window is departing Sydney 27/12/2023 + 5 days and returning two weeks after departure. Note each airline has a range of points seats, example below Qatar can range from 180,0000 to 360,000 points for a return business class seat to London. I am trying to find options at the low end of the scale.
