Qantas FF overhaul increased points, reduced taxes in Business Class

On the 3/9/19 I booked an outbound leg for travel in Sept 2020, BNE-SIN-LHR QF51/BA12 = 152000 points & $506.50 taxes. As the changes came into effect on the 18th of September, this morning I have looked at the exact same flight and flight numbers and it is now correctly 172900 points & $406.50 taxes, as per the expectations of the change.

I have been viewing return flights for when I am ready to book in a few weeks. On the 3/9/19 the LHR-HKG-BNE BA27/QF98 was 152000 points & 457.12 GBP. Over the past few days I have viewed the same flight numbers and they are now listed as 172900 points and continue to be 457.12 GBP.

I have spoken to helpful staff at the platinum customer service centre in Hobart and they agree that this is odd. They stated that while they have no control over the BA taxes the price should still be reduced, even if slightly as the QF leg should have decreased. They are looking into it. I am wondering if anyone else has had a similar experience.

At a guess I'd suggest that the taxes may be the same rate because of the wonderful extra charges to leave LHR in a premium class

Same thing happened to me with a QR booking Rome-Doha-Perth. Booked @ 104000 points/371euro. Checked after the overhaul date and points required had increased to ~130k but no reduction in fees...

Same here in relation to QR booking prior to changeover on a SIN-DOH-ROM....taxes exactly the same now on same route as prior. I understand that it is a partner airline so no real control over taxes. However, having said that, why did the points go up when the partner airline did not ask for any increase in points required??? That was certainly not mentioned in the grand new program changes...i.e. higher premium cabin points for lower taxes only being applicable on QF flights! Still what do we expect, we knew there would be no real benefit to FF's but all the way of the QF...

I spoke with Qantas yesterday and they confirmed tax reductions only on outbound flights not inbound oneway bookings and as we would expect not on partner airlines (I agree why did they increase the points required for partners when they cannot control the taxes) so my BNE-SIN-LHR LHR-HKG-BNE 2x QF 2x BA is $1116.10.(inc CC surcharge) I paid the 5k point change fee to turn it into one RTN booking which did reduce the taxes as it was all in AUD instead of the return being 457 pounds. There are more seats but not on Qantas tin so using more points with no reasonable reduction in taxes is the only option....disappointing...not surprising.
