So here's something that I think I have learned (unless someone can inform me I'm wrong) about payments to HLJ:

A long time ago I had set up someone else's PayPal account to my HLJ account (with permission of course) and forgot about it. So I bought something and wondered how I never got charged. Then I realised the old setup. The thing I bought was charged via that person's PayPal and they got the usual PayPal receipt with HLJ on it, and the JPY and AUD amounts, and the applied exchange rate. So, I went into my HLJ account and updated the Payment Method to PayPal (choosing the PayPal option and then Update Payment) and I left the Payment Currency as AUD. This opened a PayPal window for me to add an automatic biller to my PayPal account. What I didn't grasp was that the automatic biller was With Reach (Australia) Pty Ltd, and not HLJ directly. So when I bought something else next, I was surprised to see I had paid about $5 more than I expected (given the exchange rate from the previous purchase), that I didn't get the usual PayPal receipt showing me the exchange rate applied, and also that the biller was With Reach. So I went back into my HLJ account and updated the Payment Method again to PayPal but chose Payment Currency as JPY. Then, checking my PayPal account, the automatic biller showed HLJ. I then cancelled the With Reach biller.

So, I believe the moral of the story is to NOT choose AUD as the currency in your HLJ account setup, or payment goes via With Reach (through PayPal), which charges a poorer exchange rate or has some extra fee and there is no way to know how much extra you'll pay, or even how the extra was calculated. Instead choose JPY as the Payment Currency.

Also, since my items are ready, has anyone used Airmail Small Packet recently, now that Japan Post is back to normal? How long is it taking (to Perth)?
